After installing W10 20H2, get a BSOD soon after logon.  Originally thought this was a hardware issue but safe mode is ok so the search for driver/service issue has pointed to sysmain.sys which I believe is prefetch.  Anybody heard of this issue?

    Open Control Panel. Search 'restore point'. Click 'create a restore point'. If System Protection is enabled in the box that pops up, click the 'System Restore' button. Click next. Choose the 20H2 automatic restore point. Then use Microsoft's hide update tool to temporarily block the update till a future update fixes the issue. Jack E/NJ
