Blank screen deb12 after login

Hello folks,

I am facing a weird problem of blank black desktop after login at my development PC. I think there should be some problem with gnome or ? Have anybody facing same strange behaviour as me too please? Has anybody solution for this situation please? Everything is on right place, folders should be opened but no preview possible... 

Thanks for all hint,

regards

On power on while booting hold down the shift key till the GRUB menu is shown, press E, add nomodeset before 'quiet splash', press F10 to continue booting.

I experience the same from time to time.
try deleting stored session and everything will be as new again:


and then reboot
