24.02.0 Defaulting to Default theme every launch

24.02.0 Defaulting to unbearable Default theme every launch.
So I reinstalled 23.08.4, effects & composition tabs became blank white.
Restart and reinstall 23.08.4 same results, effects & composition tabs still gone.

I noticed on the web the is a solution with linux but I am on Windows 10.

Update: I deleted files at:
C:\Users\username\AppData\Local\kdenlive
C:\Users\username\AppData\Roaming\kdenlive
C:\Program Files\kdenlive
and reinstalled.

Effects & composition tabs came back.

Settings → reset configuration → should do the same.
