Upgrade to 9.0.5: Changes in layout setting fail

[agri]

Espo 9.0.5, php 8.2.5, mysql 8.0.41-0ubuntu0.22.04.1

After upgrading to 9.0.5, I cannot change neither theme nor position of navbar. In "User Interface", settings seem to be saved but have no effect. Although I change theme to e. g. "Violett", browser console still shows "body {--theme-name: Espo;}".
If I set theme to "Dark" and save, I get a black page for a second or two, then revert to theme "Espo".

Any ideas?
Kind regards

I didn't find any of the problems you described on the two test instances 9.0.5.

Try testing in an incognito tab or in a browser that is not used to work with EspoCRM. It seems that the problem is with the browser cache.
It would also be useful to clear cache in your instance Administration > Clear Cache.
