Parallels 26 VM freezes Windows 11

I have been having a problem with my VM running windows 11 freezing. Sometimes a black screen other times, it shows the windows desktop, but the VM does not respond to input. It has been a problem for almost a year. I set-up snapshots, so that if I have an issue I can revert to a previous snapshot, but that only helps sometimes and I still may end up losing something. The only thing that resolves (other than reverting to a snapshot) is a restart of the VM.

I running parallels on a MacBook Pro with Apple M4 Max, 36 GB, Tahoe 26.2. I typically do not turn off the computer over night, or let it sleep. I have tried suspending the VM or leaving it running.

 

Happened again this morning. I logged into my Mac which already had Parallels/Windows VM running. The VM is frozen. I can see the Windows desktop, but it does not respond to any mouse/keyboard input. I tried to load the previous snapshot, which saved the current state in a new snapshot. The previous snapshot loaded a blank black screen and is not responding to input.

This is not sustainable. There is clearly a problem with parallels freezing.

 

How is it possible that Parallels does not offer support for a product that is defective unless you purchase a subscription? My VM just prompted me with the following message
' "Having issues with your Windows VM?" If your "Windows11" machine appears frozen or shows a black screen, resetting it might help restore functionality. Unsaved changes will be lost" '

What!? How can this happen every other night. This product has serious problems as does parallels if they don't offer any kind of support without a subscription.

 

Turns out I have a subscription which expires on 8/29/26 for "Parallels Desktop for Mac Pro Edition". Can somebody please help me figure out why my account does not show that I have a subscription? I am entitled to full support.
