Cannot import GitHub issues since version update

[stitam]

May be related to #3712, related to #3819.

Unfortunately I do not know which version I was using which worked but I know that it broke about 1-2 months ago. In the version which worked I could open Settings for each project and set up GitHub integration there. In the new version e.g. the recently released 11.1.1, it seems all GitHub integrations moved to a new panel (Show/Hide Issues Panel). Since this update my GitHub integrations do not work. I use fine grained personal access tokens that have read permission to issues and metadata for private repositories. I wonder if I need to give more permissions to the token for the new version? I tried to simplify the "Search query to use for importing to backlog" but even as little as "state:open" does not work, I always get HTTP 422. Has anyone experienced the same issue? Is this a bug or am I missing something? Many thanks.

EDIT: This is the error message I get for one of my public repos:

GITHUB: Failed to poll new issues for backlog import – Github: Http failure response for 
https://api.github.com/search/issues?q=sort%3Aupdated%20state%3Aopen+repo:stitam/webseq: 422 OK

I'm using Debian 12 and installed superproductivity using snap.
