Keep getting error "Unable to load data: ApplicationSet <appset-name> not found in any namespace"

[vezzalinistefano]

This error keeps showing in the low-right part of the screen when opening an appset-generated app. ArgoCD still works as expected.

Also this is showing up for every app even tough I've never eneabled progressive sync:

This happened after upgrading the ArgoCD helm chart to 8.6.1.

Current versions:
