Sorry to hear that.
Since I don’t have a machine to test it, I’m also running out of bullets.
I’ve re-edited the bat file—it’s basically the content changed in the post above. It’s essentially just acting as a shortcut, similar to right-clicking the exe file to create a shortcut and adding parameters.
That said, have you tried launching it through SteamVR? In theory, OpenXR should be able to detect all VR devices.
Add the main game exe to your Steam library, open its properties, and add "-vr" to the launch options.
