Trials of Sekhemas-RelicAltar-stuck in another players instance after trade

Hello, after i traded with another player in his trials of sekhemas "layout", i cant do my own trials. Cant click the relic altar. ican see and join the other players trial even tho we are not in a party??? we were trying to finish the trial together, didnt work aswell.

Seems like were a bound for eternity..... pls sent help

Edit: joining a party with him, visit his hideout and leave the party in his hideout solved the problem.
