I fixed this issue. It is documented here.

TL;DR hyper-v kept stale info with invalid paths to the VM storage area (registry, binary blob somewhere, who knows), Docker install picked them up and didn't pre-flight check them (presumably)

Hi @jeffstokes72

I captured this as a KB - I'll go ahead and close it now. Thanks again!

Would like to note that it would be nice to provide a more descriptive message when this occurs, possibly run a pre-check to see if the Hyper-V folder exists on the system and warn if it isn't.

This issue has a label of "status/3-fixed", but I just hit exactly the same issue today. I'd also deleted the Hyper-V folder after using it in the past, and Docker crashed with the same error.

Can't believe Hyper-V doesn't realize those are wrong... Thanks!!!

did you get the directory hyper-v thinks it's using for the store? It can be changed in the hyper-v server config. Sorry for my late reply.
