World Build Test Issue

When I build and test the world I’m making (VRCSDK2), I load the world in the VRC client, but the game doesn’t seem to allow any movement at all. I am stuck floating slightly above the ground at my VRCWorld location, and I cannot turn my head (the world moves with my camera position). Moreover, when I try to access my settings menu, it flickers for a brief moment before closing quicker than I can access it. If I try to move, my feet act as though I am in freefall. This issue appeared overnight. I have made no changes since yesterday and it loaded just fine then.
