Guests: (2) Kubuntu 20.04.03 and (1) Windows 10

All is well on 6.1.26. Upgrading to 6.1.28 causes all three guests to fail on startup, with the following error message.
Code: Select all
Failed to open a session for the virtual machine | machine name |
Code: Select all
The virtual machine |machine name| has terminated unexpectedly during startup with exit code 1 (0x1).
Result Code:
NS_ERROR_FAILURE (0x80004005)
Component:
MachineWrap
Interface:
IMachine {85632c68-b5bb-4316-a900-5eb28d3413df}
Additionally, newly-created VMs exhibit the same error, so to put it bluntly, 6.1.28 does not work at all on this system.
Other than simply remaining on 6.1.26, can this be corrected?
Thanks.
ps -- downgrading back to 6.1.26 restores correct functionality, so luckily, that's easy. Also proves that there's nothing amiss with the machines themselves.
