I had that issue. I'm not 100% sure, but I find that not being in the camera screen at all helps prevent the bug. That, and/or not clicking anything after the victory text pops up. Hope that helps!
Unfortunately that is not the case. I played night 12 and I didn't use the cameras at all yet I still got the same glitch. Survive appears on screen, the UI disappears and then nothing. All i can do is interact with the plush(and not put it down) and open/close the doors which as an aside, go ahead and open/close the door over and over again. Theres a funny result.
