Everything was working today, but at some point Copilot stopped working and displayed this error. I saw that there were problems with GitHub, but judging by the status, it has been fixed, and Copilot only works through a browser, but not through VisualStudio.

[FBUtveckling]

I try to return to the prior version to the update but the problem has remained, I have updated the last version again

[makkoar]

The problem is most likely related to the server and how it processes requests.

Just to clarify, I had not updated yet when I started experiencing the problem. The update changed nothing. I tried clearing the caches/data (specifically in the following paths: C:\Users\AppData\Local\Temp\VSGitHubCopilotLogs and C:\Users\Projets.vs\copilot-chat), but it didn’t change anything.

[petrachuk]

I have the same problem today
RPC server exception:
System.Exception: Error occurred while invoking intent 'None'.
Could not parse ov

[mr-const]

I've got the same problem, tried on different computers - same story on both preview and regular visual studio 2022 (updated to the latest 17.4.16)

[Reannn22]

The issue is caused by a bug in Visual Studio 2022 version 17.14.6 affecting Copilot. Downgrade to a stable version like 17.14.5 or earlier. Clear Copilot cache folders:

%LOCALAPPDATA%\Temp\VSGitHubCopilotLogs  
<your_project_path>\.vs\<your_project>\copilot-chat

Uninstall and reinstall the GitHub Copilot extension. Make sure your Copilot subscription is active at https://github.com/settings/copilot. Wait for an official fix if the issue persists.

[dremixam]

I had the issue before I updated to 17.14.6, I tried clearing these folders also

[PyroGenesis]

Clearing the cache folders worked for me on VS 17.14.17

[dremixam]

I've been able to get copilot back by resetting my VisualStudio 2022 settings with

devenv.exe /ResetSettings

devenv.exe can be fount at C:\Program Files\Microsoft Visual Studio\2022\Community\Common7\IDE

I've lost my settings but I least I can now use it again

[hanssonfredrik]

Thanks. Worked for me as well.

[billcuda]

Tried this but the problem persists. DId you do anything else other than devenv.exe /ResetSettings ?

[dremixam]

I did a lot of the things other people are talking about on this thread and tried again after each one. Nothing worked, but when I resetted the settings with this command it went back immediately

But now it's gone again…

[hanssonfredrik]

Worked for a while, but then it stopped working after a couple of hours.

[per-ok]

Did not work.

[fastesttrains1010]

It sounds like Copilot is triggering a serialization or parsing error inside the ConversationBase pipeline, likely due to malformed or unexpected output when trying to generate a response. Since you're on a Preview build of Visual Studio 2022 (v17.14.6 Preview 1.0), this could be a temporary compatibility issue with GitHub Copilot’s plugin version.

Here are a few steps that might help:

Roll back to a stable release of Visual Studio 2022 — preview versions often break Copilot integration due to API changes.

Clear Copilot session cache: Sometimes local data causes Copilot to fail parsing responses. Navigate to %AppData%\Code\User\globalStorage\github.copilot and try clearing it.

Reinstall GitHub Copilot extension directly via the Visual Studio Marketplace, not just through the repair option.

Check firewall or proxy settings that might be affecting Copilot’s JSON-RPC communication.

I ran into a similar failure while trying to benchmark AI tools during a project on real-time train speed analysis. We were comparing models for telemetry parsing, similar to how Copilot handles streaming JSON input. If you're into how systems interpret speed and telemetry in high-pressure environments, check out this breakdown on Top 20 Fastest High Speed Trains in the World — the tech parallels might surprise you.

Let me know if you try rolling back your VS version and whether it resolves the issue!

[onlydominik]

I think it was an external problem with the copilot, after a few hours it works normally for me.

[makkoar]

It worked for me, worked for a little while, and then stopped again.

[hanssonfredrik]

Yep, it is back...

[onlydominik]

True, it worked for me for almost the whole day and it came back just a moment ago. So a typical external problem.

[smakalei]

Rolled back to Version 17.14.5, deleted Copilot, cleared the cache, reset Visual Studio settings, installed Copilot - nothing helps.

[FBUtveckling]

In my case it worked all day and now is Gone again.
My Pro account will activate in a few days with a product that does not work, how does the cost of a product that cannot be used?

[dremixam]

Same here, it's back…

[Stanisz96]

this is terrible. This bug is i think more then one year. uninstalling doesnt work, going back to prev version of VS doesnt work, reseting settings doesnt work. I gues i just need to cancel my subscription :)

[abraluve]

Same 17.14.0.. then upgraded to 17.14.6.. nothing changed

[abraluve]

It turns out commit message generator is not also working:

same

[FilipLandr]

I'm facing same issue after update to Microsoft Visual Studio Professional 2022 (64-bit) Version 17.14.6 (June 2025). Tried all suggested fixes except downgrade because I really don't have time for this. Hope that the fix will be released soon

[FBUtveckling]

Version rollback does not work to fix Copilot error

[pklosek]

Been there, done that—rolling back to an earlier version didn’t fix the issue :(

[OldShaterhan]

Related issue in wrong repository (cause for VSC instead VS2022): microsoft/vscode-copilot-release#12815

[R3ISilva]

I got the same before and after updating Microsoft Visual Studio Professional 2022 (64-bit)

[per-ok]

Same issue. (VS Code's plugin works, web version works.)

My installed version:
Microsoft Visual Studio Community 2022
Version 17.14.6 (June 2025)
VisualStudio.17.Release/17.14.6+36212.18.-june.2025-
Microsoft .NET Framework
Version 4.8.09032

GitHub Copilot 17.14.786.1071

Also not working with Visual Studio Version 17.14.6 Preview 1.0. Working with Visual code

We apologize for the inconvenience. A workaround has been posted here, and you can follow this ticket to be notified when the fix has been released: https://developercommunity.visualstudio.com/t/GitHub-Copilot-Chat-Error:-Could-not-pa/10924838

[billcuda]

This works for me.

[gabriel-sdbullion]

Did not work for me on v17.14.7

[ASOM846]

Hi guys, I am pasting solution from this thread https://developercommunity.visualstudio.com/t/GitHub-Copilot-Chat-Error:-Could-not-pa/10924838

1. Open the Control Panel
   

2. Select Change date, time, or number formats
   

3. Click Additional Settings
   

4. Change the Decimal symbol from a comma (,) to a period (.)
   

5. Restart Visual Studio
   

It worked for me, hope it will work for You too :D

[newtonknt]

Yes, it worked, but it was a very bad solution.

[mikaelservin]

It worked for me too.

Close Visual Studio
Change number format to '.'
Start Visual Studio
Change number format back to ','

That way it will not affect everything else.

[tkrasingerVN]

worked for me too, but if you change the format back to ',' while VS is running thats OK for the current VS Session. But if you close VS and start again, you run into the same problem. So the steps above need to be repeated every time you start VS.

[dudasl]

The solution is working, but it has an impact on several other programs, especially if you are in country where decimal symbol is comma instead period

[per-ok]

To ease the access to the settings, execute intl.cpl directly from the start bar, or in the cmd.exe shell you can write start intl.cpl to start it.

[tkrasingerVN]

Seems like this was fixed with version 17.4.7

[Artemik713]

Yes, Copilot is working at version 17.4.7

[syedadeel2]

Its not, it worked for few actions and then suddenly stopped and same error, and it's a brand-new window 11 and nothing else is installed on that machine except VS 2022 Enterprise.

[mikebollandajw]

Doesnt work in Version 17.14.12, such a shame to move the subscription to another provider as its quite convenient in VS

[noellelc]

Errors might manifest in the same way, but have different underlying causes. The bug identified in this specific issue was fixed several releases ago. We recommend updating to the latest version of VS to make sure you're getting the latest Copilot updates. If you're still experiencing issues, we recommend posting an issue through VS directly so we can troubleshoot if you're still having issues!
