Project Wingman doesn't launch in VR

[Us5rName]

When I try to run the GOG version of Project Wingman in vr through umu-launcher, the game doesn't launch in vr.

Using proton GE-Proton-9.5:

• When I try to run the game in umu-launcher using SteamVR, the game launches, but not in vr.

• When trying to use open composite instead (openvr to openxr translation layer) i get the following error: "opencomposite dllmain error: cannot init vr unsupported apptype 3"

  However, when I add the game to steam as a non-steam game and launch the game with
  GE-Proton-9.5 it runs without a problem in both of the above cases.

Command used to launch the game in umu-launcher:
