Cubase 12 deleting prefs everytime i close it

heres a weird one ive never had before…

everytime i close cubase 12 and restart my computer cubase 12 has no prefs saved.
so it goes to default on evetything and does a full rescan eachtime i restart.
its getting annoying that i have to set up control room …etc eachtime.

does anyone else have this problem and how do i fix it if possible…

many thanks

im on windows 10 cubase 12.0.20


To me it sounds like Cubase crashes (silently) while Quit. Are there any DMP filled in the Documents/Steinberg/Crash Dumps/ folder, please?
