Theming app makes my cloud crash

I updated to v. 14 today. Now my browser version crashes all day, but just as long as the theming app is enabled. Is there a way to set this app completly back? I didnt find a way…. Hope there is a short answer dont wanna bother you.

Error Code in Browser is 500.

hmm Maybe there is a MariaDb table?

Can’t find a factory reset for this app. Neither an MariaAB table.
