Server crash after typing on the keyboard in the vm

Hi,

I use a W11 vm with gpu passthrough from about a month and was working great.

A week ago I started the vm and when I arrived at the desktop and start typing on the keyboard the server crash, but only with the keyboard because the mouse work.

When the server restart Fix common problem notify me about Machine Check Events

I don't have idea what to do, any help is really needed 

Thanks

Config:

Ryzen 5950x (8 core to vm)

Asus ProArt x570

32gb ram 3600 (10gb to vm)

RX 6750 XT

note:

I have a Kvm switch but the problem work also without
