Temple Closes Before Lock Can Be Applied When in Duo/Group

I’m experiencing an issue with my temple in Path of Exile 2. When I play solo, I’m able to leave the temple at the end of the run and apply a lock to it without any problems.

However, when I play in a duo or in a group, as soon as my party member leaves the temple, it closes by itself and destabilizes before I have time to place the lock on my chain. What could be causing this? I haven’t been able to find any other reports from players describing this issue.

This started happening after the update that reverted the lock.

Maybe the PoE2 forums is a good place to start.
