Regression between v0.168 and v0.169, crash due to PlatformNotSupported #25899
Description
Summary
I used to be able to run Zed on my Dell XPS 15 9510, but recently it refuses to start. Bisecting shows it broke in v0.169 due to #20853, which I suppose is an intended side-effect of that change.
Steps to trigger the problem:
zeditor --foreground
Actual Behavior:

After bisecting, the first bad commit is 298b9df, introduced in #20853. There is some discussion there that it breaks Intel + Nvidia systems … well, the Dell XPS 15 9510 is apparently one of the affected systems. I don’t use the Nvidia GPU though, and I blacklist the nvidia and nvidia_uvm kernel modules in /etc/modprobe.d; everything runs fine on just the integrated Intel graphics. (It is possible that something recently changed on my system — I tried loading the module to see if it helped Zed to start, so during the bisection process it was loaded, but I think I just haven’t used Zed since mid-December on this laptop.)
I have a different, slightly older Dell XPS with Intel + Nvidia GPU, and Zed runs fine on that laptop. (I think I don’t have the Nvidia drivers installed at all on that one, but I’m not sure from the top of my head.)
I suppose this breakage was expected, though it would be nice if I could run Zed again. No other software I use (Gnome desktop, editors, IDEs, browsers, video players, games) has issues with the Nvidia GPU being present in the laptop. I’m happy to help diagnose this further.
