BF2042 Back to menu

I just can't play!
When I try to launch any game mode, a game is found, but it takes me back to the menu.
Until the day before, I installed the game and played normally for hours. After that, I turned off my PC, and when I turned it on and tried to play again, I simply can't!
I bought my BF2042 from Epic Games. I haven't updated my PC.
I've tried launching it only through Epic or only through EA. I've tried reinstalling the game. I've tried allowing specific TCP/UDP ports, I've tried changing the DNS, I've tried reinstalling EAAntiCheat, and it didn't work. I don't know what to do.

Please help me.
