VBox doesn't boot after WSL installation

[Gikone]

Hi,

I installed WSL to try Ubuntu on this system, and I also installed WSL2. When I was trying to power on my virtual machines they got stuck in the loading screen of the OS. I uninstalled WSL2 and WSL but the problem persist.
I read in this forum similar problems but never read about a solution.
I tried also from Windows Features to quit WSL and HyperV but still persist.
What should I do?

Thanks in advance!

WSL2 uses Hyper-V, which often kills Virtualbox. Follow the instructions here HMR3Init: Attempting fall back to NEM (Hyper-V is active).

FWIW WSL without the 2 does not use Hyper-V
