Docker-desktop - WSL distro terminated abruptly

It is unclear whether Docker Desktop was run on Windows or in the Ubuntu 20.04 Distribution.
I wouldn’t recommend running Docker Desktop itself in a WSL2 distribution.

When it comes to Ubuntu 20.04, it is out of support next week, see: Ubuntu 20.04 LTS Standard Support is coming to an end. Here’s how to prepare.  | Ubuntu

Solution for me: Uninstall Docker, Uninstall Hyper-V features, reinstall Hyper-V, reboot, and then reinstall Docker Desktop.
