THE SLAY ALL MONSTERS ROOM BUG IN TRIAL OF CHAOS

The problem is the room where you need to kill all monsters but there's a bug where there are monsters that spawned at the top of the platform (the one where you go up once you completed the room). So, I tried blinking over, then the platform went down, and I managed to kill the monster. The room was finished but when I stepped in the platform, it does nothing. I am stuck in that area and the switch does nothing and the only fix I found is to exit to screen/character select. But then, you cannot enter the current run anymore. This already happened twice. The second one I used a corrupted ultimatum and placed currencies. Now the run and the currency are wasted so it is very annoying.

Got 2 videos because the first one was cut idk why. But you can see that the platform doesn't go up even though the room was finished.

Edit: I also portal-ed out then re-enter the run. Only to find out the platform is still not working so I run through 6 rooms to just go back the platform that was not working.
