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...

I am running Parallels on one of my computers and since I updated the machine to macOS Big Sur (Developer Beta 1) my virtual machine with Windows 10 doesn't start anymore. The VM is not super important to me so I don't want to put any work into getting it running, but it would be a nice-to-have...
