Thank you in advance.

I have used win10 VM for years with no issues but just a few days ago it stated booting into a black screen after login.

This is also happening to a windows 11 vm. This is using virt manager for both VM's.

The win10 I have had a very long time with no issues until just a few days ago it boots to login screen, then after login the screen turns black.

The win11 vm was created about a month ago. It was also fine until a few days ago. I am on ubuntu 22.04.4 LTS.
