Stupid new Parallels Win 11 ppm just crashes all the time. 4 times with support ALL GARBAGE responses from a very lame company. Have been with this company since the beginning. I am done. I hope they go out of buisness.
I'm not with Parallels, but I had a lot of freezing and crashing until I'd set my macOS anti-virus app (yeah some of us run an anti-virus on our macOS setups) to exclude scanning the PPM file. It's a fairly large file and the scanning of it will have a significant performance impact.
