OVPowerPlay I haven’t used the game but when I’ve had issues that sound similar to this it’s involved one of two things. Either OpenXR needed to be selected as an option in Steam VR’s setting (this might now be default, I don’t think I’ve noticed the option lately). Or more recently, issues where hands appear on the floor, going into Steam VR settings, Video, and then unclicking ‘turn off headset when idle’, fixed the issue.
Otherwise I would reach out to the developer (ARVI?) first, since it sounds like a game issue more so than a platform issue.
