Getting sent back to main menu after joining game

As the title suggests, whenever I try to find a match the screen fades to black as if trying to join the game. I get a Loading screen with the BF6 logo, and then it sends me back to the main menu. No message, no error code, just that.

I've tried reinstalling, repairing, disconnecting internet, but nothing works. Any ideas?

(Issue is on PC but I have seen reports of the same issue on Xbox and Playstation)
