Glitchy Trapdoors

Just going into my house when I open the trapdoor while climbing stairs, all of this in a formation of a vertical stair track with trapdoors on the sides every floor.
Then I try to go out but glitch a bit through the stairs. Then I close the trapdoor and I can't open it again because I keep falling into it without suffocation and with the camera being unmovible. I rarely fix this by moving the camera a LOT without disconnecting.
It's really annoying.
