    I've updated Parallels Desktop to Version 20.3.0 (55895). After the installation of the Parallels Toolbox Update in my Windows VM (I'm on Windows 11 ARM on a MacBook Pro M1Max), I can't boot anymore. It says: No OS installed. My VM was working fine for the last years, so no clue what happened. Glad I had a Time Machine Backup, but also the Backup stopped working after the Update. Any suggestions?

    @SamuelS16 Does this issue still happen on Parallels Desktop 20.4.0?
