4.20 causing BSOD

berniestafford_c960b5afba

Yesterday I upgraded to 4.20.  95% of the time that I try to use it, either during or immediately after a render, I suffer a BSOD with the error code "clock watchdog timeout", which apparently refers to some sort of cpu issue.  It's locking the PC, forcing me to do a hard restart each time.

Never experienced this with any other software, but with 4.20 it's almost guaranteed.

19-11900k, RTX 3060 / 12 gb, 32 gb ram.  Latest version of W11, all drivers up to date.

Any known solutions out there?

Thanks.
