Stuck in Lobby – Game Returns to Main Menu After Starting

Same here PS5, I've been trying for 3 hours, even reinstalled the game but nothing happens 

Stuck in lobby, won’t let me start a match or even a count down for a match. 

Same on PC and XSX

The problem may be that you are using mobile internet (not fiber). Foreign thread with similar problem, there is a solution there:link

So, i think it has something to do with anticheat system. I had a diagnostic app running on my second screen cause I've been having some really bad load speeds even when im just scrolling through YouTube, so I was watch my core count and crap to see if i had something wrong with my cpu or if my pc if really bottlenecked. As soon as I closed that background app it let me play. So in my opinion some of our background apps are triggering the anti cheat system. At least thats how I fixed this issue on my end. Kinda crappy, you'd think it would know the difference between a diagnostic tool and a hack app or whatever lol

I have the same issue on Xbox

Update: eventually causes game to crash on PC.

After attempting to join a game of conquest, the game returns to the splash screen in a type of infinite loading screen.

Same here on Xbox SX

I'm having the same issue, been going in circles for the last 20 minutes on ps5
