right at the beginning of the game I cant go downstairs. I can leave the toilet, enter my room,
but I cant go downstairs. When I try to go down the stairs nothing happens and the controlls are
suddenly broken. I cant open the menu and smartphone, also I cant interact / open doors anymore-

Playing on Win10, already tried different resolutions, switched between fullscreen and windowed
mode, but nothing helps.

Is there any way around this?
