VirtualBox starts up OK. Failed to open a session for the virtual machine. Result Code: E_FAIL (0x80004005) Component: MachineWrap Interface: IMachine.

I am experiencing the same problem as #20191. VirtualBox starts up fine. Existing VM fails to start with same error as this ticket describes. Failed to open a session for the virtual machine C7. I have attached the log file, in addition to pasting it below.

The virtual machine 'C7' has terminated unexpectedly during startup with exit code 1 (0x1). More details may be available in 'D:\VirtualBox VMs\C7\Logs\VBoxHardening.log'.

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

I have tried some suggestions found using Google and sometimes they help, but next reboot or start of VirtualBox results in same bad behavior. I also have uninstalled VirtualBox 6.1.18 and re-installed. It sometimes seems to let the VM start up and other times the same error appears. Both the install of VirtualBox 6.1.18 and the startup of VirtualBox 6.1.18 were done as administrator.
