8.0.20 - Crash upon quitting.

I’m experiencing crashes upon quitting since 8.0.20 (with Cubase 8.exe staying in the task list, have to kill it manually most of the time).
The result is the software “forgetting” my extra plugins locations (other than the default ones), so I have to set them again, quit, reopen, rescan and hope for the best since sometimes auxhost.exe crashes on startup and make Cubase crash as well.

I tried to uninstall the whole software, wipe clean pref folder but nothing changes.
I thought the problem came from my bridged 32bits plugins but even excluding that folder crashes happen even on startup.

Thank you in advance for your help and investigations.
