I cannot properly sign in into GitHub.

I cannot properly sign in to GitHub. I keep receiving this warning message: GitHub authorization needed: Sign in to GitHub to continue. The app lost access to GitHub.

Pressing the Sign in to GitHub button does not help. Even though everything seems to be working correctly. Like the authorization flow successfully completes.

The health check window in the app also shows as successful, and apparently everything is healthy. Still, I cannot use the chat view or create automations; model selection keeps saying "Loading models...".

From the health check:
