I upgraded from v11 to v12 Parallels this AM, and 1 of my 3 VM's now blue screens on boot. I've attempted to correct by switching to 1 CPU (was 4 originally), and switching to Apple Hypervisor from Parallels. Making this changes the STOP error, but it still blue screens. I've also done a "First Aid" routine via Disk Utility on the hard drive, so it's not an issue. I use this VM daily for work, and now it's dead to me, just because I updated to v12. How do I get my VM working and get back to work? Any assistance at all will be great appreciated.
In case this benefits anyone in the future, I'll try to keep updating this post. Support has connected to my machine, and were unable to solve it, although they basically did everything I did plus set the RAM for the VM to 512MB (From 4GB), and have escalated the issue, collecting a memory, dump, logs etc.
