Win10 VM can be booted only once, after that hangs and crashes Unraid

[tampano]

After learning Unraid and solving the tricks on how to passthrough a 5600G iGPU, now I'm facing a very weird issue: if I launch the Win10 VM everything is fine. When I stop it or restart it, the screen stays black (once i could get to the machine with Splashtop, but i think it was random, never happened again), there's one CPU (only 1 of two paired cores) that hangs at 100 percent, the only solution is rebooting Unraid, sometimes also because the entire Unraid becomes unresponsive (once the entire VM tab disappeared).

 

Any idea of the direction I can look into? Thanks.
