Nothing in the logs show anything related to this issue.
Can you post a screenshot of what you see? I'm no Musescore user so no idea how to actually work the app, but the image below shows what it looks like here.

Since you did mention using other profiles for the app (appimage), have you tried using Musescore from the repo with a clean, new user?

Yes, I used a clean install from the repo and got the same result you did. In fact, I used your picture and circled the problem I'm having. You'll see that clicking the "Mixer" button does not bring up the mixer, and the playback controls are not functioning. Those playback controls should be moveable by dragging that :: area, too. Perplexing! Thanks for your interest in figuring this out, btw.

Yes, I used a clean install from the repo

For future reference, no need to reinstall at all, just go to systemsettings > users > add a new user and log in as that user.

Good to know the actual issue & issue is present here, so now I can debug locally.

Running from shows an issue with libMuseScoreSamplerCoreLib.so :

Appimage includes the needed closed source sample files, which is in debate as being a violation of the license:
https://github.com/musescore/MuseScore/issues/15706

But the real problem is what I missed in your first post, it only works with a real ancient Qt6 version (6.2 is from 2021). Checking the upstream bug reports, there are tons of issues reported with currently used Qt versions, so it looks we'll have to wait until all is sorted upstream for Qt 6.9:
https://musescore.org/en/node/379819

So, this does not look like a KaOS (packaging) issue, but rather a known upstream issue. Issue will stay open here so progress can be tracked.
