We hide the Medium folders from the asset browser when you browse through C:\users\ or D:\users\ because we already provide those same folders with "Personal" or "Exports."
Recursive browsing also produces a lot of problems, as evidenced by your crash on the D Drive. Could you send your logs from crashing? (Just crash Medium and send the most up to date log, sending through multiple non-related logs is a headache for us) You can find log files from C:\Users\username\AppData\LocalLow\Oculus\Medium\log and send to medium@oculus.com.
The session that you *just* did will be the first log (called Oculus_Medium.log), and the session before that will be .1, the one before that, .2, and so on. I'm looking for a log during a session in which you crash. Hope that helps!
