Whonix Workstation terminated unexpectedly error (with VM 6.1.16 & 6.1.14)

This is not an issue which could be caused by anything Whonix is doing. It’s an issue with the VirtualBox host software.

Kicksecure ™ in VirtualBox - Troubleshooting - Kicksecure ™ does not Start?

Try a non-Whonix VM

  1. “Forget” about Whonix ™ for a moment and imagine you had never heard of the platform. Test the VirtualBox host software first.
  2. Try a VM other than Whonix ™ such as for example Debian buster .
  3. If that does not solve, resolve as per Free Support Principle.
