Hello @Zhekaf Meman (IRQ) ,

These are some things I would check:

• Upgrade the virtual machine version:https://learn.microsoft.com/en-us/windows-server/virtualization/hyper-v/deploy/upgrade-virtual-machine-version-in-hyper-v-on-windows-or-windows-server
• Temporary remove the virtual switch associated to this machine
• Search and delete Saved State for that machine (if any): https://learn.microsoft.com/en-us/powershell/module/hyper-v/remove-vmsavedstate?view=windowsserver2019-ps
• Ensure that the VHD is not attached to any other VM
• Check if available RAM is enough for the VM settings
  -Retry a VM restart using Powershell (ad Admin): https://learn.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2008-R2-and-2008/dd581971(v=ws.10)?redirectedfrom=MSDN

Further than that I would recommend to check System, Application and HyperV role logs for more information.

Hope it helps in your case,
Best regards,
