Hi Nicolas,
Not sure why you would still be seeing a GSOD as that is generally only applicable during the Insider testing stage. It changes to BSOD at or near public release. This is the norm for every version that has come out since 2014.
Been an Insider since day 1, and going through the whole 20H1 cycle, only had a few minor issues. Some like Disk Optimization retaining last run info was never fixed prior to going to Release, even though MS fixed this like 5 months ago in Fast Ring (Dev Channel).
The CU's that have been coming out lately, have made the system quite unstable now. Since updating to .388, have never seen a freeze before. Working away, a simple mouse click, bang, BSOD or a total freeze.
I do run several programs at the same time, heavy multi-tasking, but the amount of work I had to redo due to these crashes and freezes is unbearable.
Regards Nicolas and have a great weekend,
