I can tell you this is NOT only Dell computers...
I agree, I have seen it on Asus and Gigabyte Motherboards... Mainly I7-6700 CPU's (apox 100 rebooting daily)
For me "So far" I've Only seen it with 32bit version of windows 10 and using the "Microsoft NVM Express Controller". (but that is most of my WAN)
As documented if I switch to the Samsung M.2 Driver everything works perfect.
Also don't know if it's relevant but my boot partition is NOT the first on the disk\ssd.... and typically DELL and HP's also have their own recovery type hidden partitions.
Not sure why ProxMox VM's would fail.... I've tested 22H2 (x32) with 2022-10 on a HyperV and it worked find... and a new install on Gigabyte metal crashes.
It would be helpful if everyone having this issue could respond with their Computer model, Windows Version (32\64) and boot drive model.
