unable to queue to Cup

I dont think this is the right place but since i saw something similar like this on here and the dedicated Fortnite Support doesnt help i need to try it here. My Friend and I wanted to play the division Cup 3 together with an other friend. but One had a problem. He has 14 cups so no lock on the cup and has every tick with secure boot and all that. when we wanted to queue tho he became a error mathmaking #2 it said unable to play this gamemode at this time. we Tried so many things that we found. and like i said the support didnt really help they just said we have to solve by our self… when he restartet fortnite he got the following message from easy anti cheat we think it has something to do with this but we have no more ideas.
