Abyss Bossfight bricked by standing in center

Hey this has probably already been reported a ton but i didn't see anything about it on the first couple pages so, yeah i was doing the abyss bossfight the final one where the floor splits and my character is stuck on the split .

Here's a screenshot, the volatiles cant kill me either since there's no floor i guess.



I can respawn at checkpoint but that's not happened in quite a few fights.
