I've finished to classroom, the door is open, but I'm stuck, I can't get out. Has this happened to anyone else?

My PC restart automatically after loading (after the Carl Jung Sentence).

So i got to the point where i was at the boat irl. I couldnt figure out what to do, so i went back to the hospital and looked at the kids TV. it was at the boat, but i couldnt do anything at all. I held R to reset but it did nothing. So, I restarted the game. Now the elevator isnt even open for me, and I cant go back to the cabin......

Stand up, get out from under the bed, crawl out from under bed, east, west, north, south... nothing works. How do I get out of here?
