Windows 10: Windows 11 BSOD Inaccessible boot device

HelloThis is the 2nd time I've tried updating to Windows 11. First time I've tried it few months ago, I got BSOD when booting up with the issue "Inaccessible Boot Device". It got so bad to a point where it couldn't recover or rollback the issue and I ended up having to format my whole PC and reinstall Windows 10.I tried it again for the 2nd time I got the same BSOD issue "Inaccessible Boot Device" but thankfully was able to rollback to previous state.What is the matter and how do I fix it to successfully use Windows 11?FYI, my computer is brand new, built this year running on X570 MOBO. BIOS

Windows BSOD - Inaccessible Boot Device

Ever since December after a windows update, any time I re-boot I get a BSOD - Inaccessible Boot Device, and have to go back to a restore point. Currently my update log shows KB4054517 failed (0x80070643 on 12/12/17, Cum update on 1/5/18 filed then succeeded,
and all future updates through Cum update KB4056887 on Jan 19th succeeded. Windows runs fine with no errors, but having had to go back to a restore point 6 times in the past 6 weeks, if I reboot I will get the same BSOD and have to restore again. Any suggestions
on how to fix the inaccessible boot device error I keep getting??
