in what ways VMM raises an error on WSL? Could you show a full traceback to what you see?

Asking because we were told that VMM is supported by the Windows WDDM driver mode (#968 (comment)), and WSL is a pass-through of WDDM according to @ksimpson-work, and so by deduction it should be supported. This is a bit surprising... 🤔
