Trial of Sekhemas, second floor door stuck in unlocking animation

Used an ilvl 62, 3 floor key with another player in my party. After killing the boss and buying a couple of boons, tried to open the door to the next floor and on clicking the door it became stuck in the unlocking animation, repeating in an infinite loop.

I still had keys, but it now says "This action is no longer valid because the next room has been opened"

Update: I was able to get back into my trial by restarting, failed to join instance on load, and in the new instance start the trial on the second floor. Thank you GGG for implementing this feature <3
