I am on Windows 11, have Dokan installed, and downloaded the compiled mtpmount-x64.exe. It does not provide any output so I can't tell if it is working. There's no automatic "usage" output like you have on most command line utilities, no "version" or "help" from what I can see. All I get is no output.
I'm following the instructions you have in the repo, and I cannot list available devices even though it's connected. If there's an error, it's being swallowed.
