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

Try a non-Whonix VM
- “Forget” about Whonix ™ for a moment and imagine you had never heard of the platform. Test the VirtualBox host software first.
- Try a VM other than Whonix ™ such as for example Debian
buster
