Poe 2 sanctum/trials of ascendancy on 3rd trial bugged.

I can't try to finish my 3rd ascendancy at the horrid and awful sanctum trial, because of this.



How does one even change instance in the middle of a sanctum run? In my case it being the third floor run.

And because of it my run is now harder as it chose an option I would've not chosen on this unfun mechanic. So what am I supposed to do now?
