macOS Monterey - VM on physical external disk not running

Hello,
I have an issue with Parallels Desktop 17.1.1 (51537) and macOS Monterey 12.1. On Big Sur, I used to have a Windows VM with its HDD set as Physical External, referencing to an external SSD with a Bootcamp partition. Since I updated to Monterey, I get the following error (translated from Italian, may not be correct word-by-word):

I tried:

• Recreating the VM file;
• Using "External device" as boot device (VM EFI says it cannot boot this kind of partition; setting
  Code:

  vm.bios.efi=0

  does not solve);
• Checking if Parallels has full disk access in Privacy settings.

I know a fix has been released for "traditional" BootCamp set-ups, but it didn't solve my case.
Thank you in advance,

Daniel

 

... anyone?

Hello, I had no reply at all. Any news about this? Parallels is almost useless for me now, and I'm a Pro user. I'd expect at least a feedback.
