Bug: queries not shown in settings after project is renamed

Quick tipp

If you are stumbeling over the same issue, see the workaround solution here: https://github.com/edtro/EdTro.AzureDevOps.Extensions.querybasedboards/issues/47#issuecomment-812130248

Original request

I've created a couple of shared queris in a project and none of them is showing up in the project settings to allow configuration. I guess there is something screwed up but I don't know exactly where to start. I've a couple of projects where I've done similar setups and it's working quite well.

Special in the affected project: it has been renamed.

Other inputs or hints: in the development console of the brwoser I get a 404 when I want to open the settings:

GET https://server/collection/_apis/ExtensionManagement/InstalledExtensions/realdolmen/EdTro-AzureDevOps-Extensions-QueryBasedBoards-Public/Data/Scopes/Default/Current/Collections/querybasedboards-import/Documents 404 (Not Found)

When I run a query and click the "show as board" button there is a super quick error message I'm not able to capture. In the developer console I see a bunch of errors:

ms.vss-web.platform-…jTC5yBclkr.min.js:1 POST https://server/collection/_apis/ExtensionManagement/InstalledEx…copes/Default/Current/Collections/querybasedboards-configuration/Documents 400 (Bad Request)

Could not create configuration for query: ee5fca6e-219e-4811-a071-4bedefa767da

GET https://server/collection/_apis/GraphProfile/MemberAvatars/win.Uy0xLTUtMjEtMzMwMDg0MjA5Mi04MTkxODE4MjUtMjEzMzgyNzUzOC0zMzg1MQ 401 (Unauthorized)

(I guess the last one is not relevant, only to be complete)

What I also can say: I can add the global config but it is not repected in the queries.

Please let me know how I can help to investigate further.

EDIT
Just found out a very important thing I guess: I had a collection backup restored as test environment before we renamed the affected project. And before we renamed the project the queries have worked propperly. So I assume that this is linked to renaming projects.
