Starting Windows VM, Powers Down PC After attaching GPU

After attaching my Nvidia GPU ( Which is not hidden from dom0 ) to my Windows VM When I start the Windows VM, my computer powers down.

Shouldn’t anything in a VM not be able to physically affect my computer? Could someone mimicking these conditions remotely power down my computer?

Qubes 4.2.1, Latest kernel, Test Release.

If the pass-through isn’t done correctly, your system can crash when you try to use the GPU from a qube.

It happens because you didn’t hide the GPU.
