An input issue makes the game unplayable, you can't walk or turn.
With the Valve Index, you can’t walk or turn, the left and right thumbsticks do not work. When you go to the bindings window, the game name appears as “OPENXR TEST INSTANCE”. This way the game is utterly unplayable and can be considered BORKED. Opened a bug report at https://github.com/ValveSoftware/Proton/issues/5192
Several other games face a similar issue, including the “OPENXR TEST INSTANCE” classification. Valve never explained that.
