It is just simply because of the reason the devs leaving OpenVR and OpenXR runtime-plugins inside the gamefolder, even if they serve no purpose (it does NOT have official VR support).
Could have been easily solved years ago (according to posts like this, this issue exists for quite a long time), and has nothing to do with "updating to a newer unreal engine version".
OpenVR and -XR plugins need to be added MANUALLY to the projects cluster (.uproject meta information). UE does NOT do this by its own.
Game devs need to clean up their projects and keep them clean, after fiddling around with possible additions to their game and yet deciding NOT to overtake those ideas. It is a simple check-off.
The sheer ignorance of the people here on this sub is baffling me. "Mih dunt haz proplem, ju dunt haz proplem". Are you guys really this narrow minded? There IS a problem SteamVR starting WITH the non-VR game, due to VR/XR plugins being present inside the game folder, which cannot be removed to hinder this application boot-call, otherwise the client will crash. You cannot be this stubborn ... on the other hand, most of you are probably even some dull minerals after all.
