Failed to open a session for the virtual machine #VMName#.

VirtualBox-6.1.32-149290 works 100% and all VM's start.

From version 6.1.33 get the following error on ALL VM's:

Failed to open a session for the virtual machine #VMName#.

The virtual machine '#VMName#' has terminated unexpectedly during startup with exit code 1 (0x1). More details may be available in 'C:\Users\#UserName#\VirtualBox VMs\#VM_And_LogFolder#\Logs\VBoxHardening.log'.

Result Code: E_FAIL (0x80004005) Component: MachineWrap Interface: IMachine {85632c68-b5bb-4316-a900-5eb28d3413df}

Tried Installing 6.1.33 with and without Extension Packs - Error as Above Tried installing 6.1.34 with and without Extension Packs - Error as Above Tried installing 6.1.34a with and without Extension Packs - Error as Above

Please note: I don't think it is the Extension packs because running v6.1.34a with Extension Pack 6.1.32 gives same error.

Included is the LOG files for: Successful start and shutdown of a VM (v6.1.32) 1.VBox_20220620_6.1.32.log 2.VBoxHardening_20220620_6.1.32.log Unsuccessful start of same VM (v6.1.34a) 1.VBoxHardening_20220620_6.1.34a.log
