Possible HACKER needs attention ASAP!

I went to trade a Japanese player on poe2trade for a relic to do a Trial of Sekhemas. After the trade was complete, I left the party and was unable and currently STILL unable to do my own trials run. This same player who traded me also CONSTANTLY keeps appearing in my game after he finishes his trial This leads me to believe he somehow hacked my trial attempt. I tried everything from logging out/in, closing out of the game, joining a new party, finishing a map, talking to NPC's and NOTHING has worked. Same player is still seen in my game when I travel to Trials of Sekhemas and I'm unable to interact with the relic statue to start the trials. I took a screen shot of the player. Please look into this matter and provide any info anyone and EVERYONE.
