I am stuck in someonelse trial of the sekhemas instance

I did a trade at trial of the sekhemas with a guy, then i am stuck in his instance. I couldn't fix it for an hour and so.
What i tried is;
- Logged out and login with different server
- Teleported to my friend's sekhemas instance and go back to Ardura Caravan then left party and tried again.
- Closed the game for 15 min to see if the instance automatically removed.
- Changed character and teleported to trial of the sekhemas which creates its own instance without a problem.

Same here, i just did a trade. and facing the exact issue.
