Cannot connect to Internet from WSL2

The issue described in #5821 is showing up again!
Although, the adapters don't show up as disconnected, still ping example.com does not work anymore.

Ok, I just re-enabled Hyper-V and Windows Hypervisor Platform and everything works again.

EDIT: After a reboot it stops working again

I recently moved my WSL distros to WSL2, suffered the network problem and noticed I was in stable Version 2004. I updated to the latest release in the official/stable channel (Version 20H2) this morning and everything is working now.

Maybe trying to move to 20H2 can fix the problem but I do not know how hard it is to move from a more recent Developer Program version to the current stable one.

EDIT: That version change is possible only with a clean install, but if you do need your WSL's VM networks working is the only choice until the next Insider Program patch

I figured that BitDefenders Firewall is blocking all WSL2 traffic.
