Hi Josef,

It actually might not be that much of a long shot.  I am using WSL2 on 
Win 10 Pro, and I have had trouble with connecting my VS Code Remote SSH 
to my VirtualBox VMs.  Standard ssh from the command line works, but 
vscode remote ssh doesn't connect (when it used to).  Also having issues 
upgrading an Ubuntu 20.04 VirtualBox VM.

Might try disabling disabling WSL and see if that improves things.

Brendan.
