THIS IS THE OFFICIAL FIX (FINALLY!):
I got my Lenovo PC which had the same issue back after I sent it in 4 times! I pushed them very hard to fix this. And FINALLY they found the issue and the FIX (or at least a very easy workaround)!
They wrote:
Dear customer,
please do NOT enable "NVIDIA USB 3.10 eXtensible Host Controller -1.10(Microsoft) in device manager. This disabled device is part of NVIVIA driver and is not present in your system, therefore causing conflict with other drivers resulting in freezing and stop errors (BSOD).
Lenovo is in the meantime working together with NVIDIA on resolving this issue releasing a new driver that will fix the issue.
If you proceed with recovery or new installation of the Windows operating system, please always disable this device in device manager!
Working with the PC on Windows 11 with the newest NVIDIA drivers (512.15) for two days now without any issue, before this it was crashing at least twice a day so this is definitly a "workaround" without negative side effects, which fixes the problem for now. I am sure everybody who has the same issue will be very happy about this. This post has >11000 Views so there must be quite a few of us...
Here is how this disabled host controller looks in my device manager:
Happy Easter!
Update: 1 Month now without a single freeze. This is the solid fix.
