Since a few days my installation “randomly” freezes, and only way to get back to it is an hard button reset
It is not completely random since it appears to me that while using it freezes very rarely but it freezes almost certainly while in screen saver, not actively using the PC.
I already tried rolling back to 5.4 from 5.9 but it didn’t fix the issue
Only relevant system change made recently is that i installed Nvidia 390 proprietary drivers
