If you're on PC and your view continuously moves in a single direction or you're stuck moving in a specific direction, you may have a game controller or other input device sending input to VRChat.
Please make sure to unplug or disable any extra input devices or game controllers you're not using. This includes Xbox controllers, DirectInput controllers, HOTAS and Joystick controllers, virtual joystick/game devices, and other non-standard input devices.
These can all interfere with VRChat's input methods.
