In fact, for anyone having a hard time with this, the solution is usually to run the application with normal (non-elevated) user privileges if possible. I had the same problem with SyncBack Pro, which needed to run with admin privs to backup open/locked files. Once I ran it without those privs, I could access my cryptomator drive but I of course lost some of the other advantages. What I still don’t understand is why I can type the drive letter into explorer (which is running unelevated) and it resolves correctly but I cannot type the UNC path into explorer and get to the drive. This is the very same UNC path listed next to the drive letter.
