I updaded my laptop to BigSur developer beta 3 last night and now Parallels fails to launch with the error below. I've tried deleting and reinstalling, but the installer gives the same error. And the "Check this solution" link is a joke. It links to the KB home page and not to a specific article. Anyone else experienced this yet?

This has worked for me - previous article I found had systemversioncompat without underscores. Adding to bash profile did t work but made a launching .command file that sets this before calling Desktop with -a
