    Hello.

    My Parallels setup has two older Mac OS X virtual machines (for old software that doesn't run on modern macOS). One PVM running Mac OS X 10.9.5 and one PVM running Max OS X 10.11.6. Neither of the two PVM's boot under Parallels 20.0.0-55653, only showing a black screen.

    Fortunately reverting back to Parallels 19.4.1-54985 helps getting up-and-running again.

    Is this a known issue, will it be fixed in a coming update?
