Vagrant Mounting issues on Win10 20H2

Greetings list. I’m running the current versions (as of 21 Feb) of Vagrant and Virtualbox

I have an issue with a Linux vagrant box that’s worked fine for years but as of late (it seems with the 20H2 update but I cant say that with certainty), when I build a new VM with vagrant up it will build normally after which i can SSH into it just like I have always been able to however after the VM is shut down (with HALT or SUSPEND), the following attempt to bring it UP again results in an endless loop of a timeout after the Private Key message. Looking at the Vbox windows, i can see an error mounting /vagrant but I really have no idea where to go from here…
