Been having trouble with gpu passthrough on Bazzite

I've been trying to get gpu passthrough to work on a seperate installation of Bazzite and I've just hit a dead end. I followed the guide after enabling the vfio drivers with no obvious errors, but when I get to actually creating my vm I hit a weird issue. When I add the gpu to the vm I get an error that reads:

Error starting domain: Internal error: Unknown PCI header type '127' for device '000:10:00:0'

One weird thing about this error is that it doesn't happen when I start a vm after a reboot, but if I try stopping then starting the vm up again, I get the error every single time.

Has anyone encountered an error like this before? I tried looking it up online but unfortunately all the posts I could find were for distributions other than Bazzite. I should also mention I'm using a pcie riser cable to connect my gpu to the motherboard but I don't know if that's causing the issue
