I was using the parallels until march, 18th. All of the sudden it stopped and the screen just stays black. My signature is ok until 2026 and there were nothing aparently wrong, but now I can't use it.
I just run into the same issue today. Try reverting to old snapshots and it didn't solve the problem. The only reason I can think of is Sequoia 15.3.2 update.
Same with me. The windows applications -File Explorer etc try to load (there is a move to load the icon onto the toolbar byt stop.
Here is more I've found related to the issue: 1) Even though there is a black screen, the VM is running. It's only File Explorer crashed. 2) Task Manager can be launched via ctrl-alt-del, and via it File Explorer can be relaunched. The desktop will reappears but task bar is not responding. 3) Other applications can be launched via desktop icons or Task Manager. 4) Rolling back to pervious 24H2 snapshots doesn't resolve the problem. But, rolling back to a snapshot with 23H2 resolves the problem. I'm on latest version of MacOS and Parallels desktop. It seems to be an issue between the latest MacOS 15.3.2 upgrade, Parallels hypervisor and Windows 24H2.
