Trial of chaos bug - coop unable to start last trial

Today, after patch, encountered a bug in trial of chaos. When in couch coop activating the last trial (10 trials) lest you in to the first room, bet cannot select the first modifier. It just shows in chat: You must be the map owner to do this. Tried multiple times, doesnt work. Player 2 cannot activate too. Tested and opened first trial, everything worked, so seema like the last one is bugged by some reason. Hoping for a quick fix.

Same issue here! We couldn’t even find a way to let us get back into the trial (we are only doing the first level trial of chaos so we were just trying to restart the whole thing)

Couple of days later and bug is still there. Now it is impossible to pick first modifier in every trial, so it doesnt matter if its 3,7 or 10 trials. So it is impossible to play trial of chaos in couch coop. Dont know what triggeres it, becouse it was doable before.
Also in trial of sekhimas 2 times we have failed in floor 4 with still over a half of honor left and full hp. Charecters (boths p1 and p2) just ranomly faill the trial. So atbyhis point it is impossible to finish and get 4th ascendancy in couch coop. I hope this will be adressed soon.

not exactly same problem. completed the trial for ascension, but before i could choose skills the game crashed (said trial complete before crash) now it wont drop new inscribed ultimatum, so cant get the ascension points.

Having the same issue, completely broken as of now

Saw a post on reddit (repost of this thread) about this. Looks like other people have the same problem and the newest update haven't fixed this. Only solution to this at this time is to do trials separately (each character individually). This could take a lot of time and be very hard for characters that are not uber geared. I have no idea if couch coop is possible when fighting trial master, but because he is accessible only after finishing 10 trials, looks like he cannot be killed in couch coop as well. haven't seen official statements from GGG about this, so I can assume that this is not a priority and probably will not be fixed in the near future. We couch-coop enjoyers will just have to do trials separately for now ore just play without them.

Same issue.
