Today's new VirtualBox test build 6.1.35 r152011 release works with Hyper-V enabled like the previous test build ( r151866). If you need VirtualBox and WSL2 or Docker then you should try it IMHO as the 6.1.34 does not support Hyper-V that WSL2 or Docker require.
If you do download the test build then make sure you keep a copy of the file(s) in case you need them as you cannot download them once a later test build is released.
The test builds can be downloaded from the following page:
