SteamDeck(SteamOS) can't read path with RouteViewer

I bought SteamDeck.
I tried to enjoy OpenBVE right away, but OpenBVE worked fine with Proton like this, but RouteViewer couldn't read the object because it didn't recognize the path.
It's ArchLinux based, but OpenBVE and RouteViewer doesn't recognize the file path.
I would appreciate it if someone could give me some solution.

I'm sorry.
I think my problem is probably broken paths when going through sshfs symlinks.

It was a simple mistake not to include the Object folder in the mounting location.
I'm sorry.
If you register OpenBVE as a non-Steam game, just set Proton to 7.0-5 to play.
Register RouteViewer in the same way.
The data reading speed of RouteViewer is twice late as slow as desktop PC.
Other than that, GIMP, Blender, and LibreOffice work, so you can use it as a development environment.
network mount is
sudo mkdir /run/media/share
sudo sshfs username@192.168.x.xx``:SHARED_FOLDER_NAME_OF_SERVER_PC /run/media/share -o allow_other,follow_symlinks
Server PC login password is required.

A new style that has never existed before, "BVE while lieing" on SteamDeck.
Assign keys to the controller and drive while lieing.
It feels as if the Tohoku Shinkansen driving software came out on a game machine.
