Proxmox crashes/becomes inaccessible when stopping or restarting windows vm

[Lavan]

I'm a new user of Proxmox and have created a vm for my Unraid nas and one for Windows. Whenever I try to stop or restart the Windows vm, either using the qemu agent or directly in Windows, Proxmox becomes inaccessible and I have to reboot the entire system. To Windows I have passed through one nvme, an arc a750 Gpu and the Intel audio controller as well as a few usb ports. Configs and settings below.

Intel i9 14900k
MSI Z790 Tomahawk Wifi
