Well, this sound a lot easier! ;)
One thing I still wonder though, is if we deleted the vm disk for a vm in rescue mode why does it try to passthrough the pcie device anyway when attempting to boot the vm?
I mean, there is certainly an order in which a vm verify if it can boot or not, no ...
Alright, so the file system is not corrupted. After some tests I understand better what happened.
When I first encountered the problem at boot, I deleted the VM disk file in rescue mode thinking it would prevent the vm from autostarting, but it did not. Although I'm not sure why, without...

Right now on proxmox 7.0-14+, I am able to pass through a Nvidia GPU without any issues, but when I pass a complete USB hub to the windows VM via pcie passthough I get data...
