I don't know why my character keeps changing position and every time I move it seems smaller and smaller until it's at ground level. Also, my hands get stuck and it no longer detects the controls after a few minutes of play. It's on the lowest quality and the game still crashes. Is there anything I can do? I think this isn't compatible with my quests.

Hello, from what you described your controller must have ghost triggering, you can try playing with just 1 controller or with hand tracking . What device do you have? 

I have meta quest 3, the main problem is that when I teleport, the position of my character goes down more and more, until it reaches the floor level, is there any configuration to reset to the original level, because I can't find it, to fix it I have to close the game and open it again, the control detection only fails in this game, everything else works correctly for me, is there something I can configure to make it playable, since I can't pick up things from the scenarios like weapons because I can't reach them
