Having some of the same issue.
Started thursday 13 feb when windows got updated and a new nvidia driver was available, got worse yesterday. Don't know what got installed first.
Mostly the game closes on start up or when loading a map.
The game gives different types of DirectX errors, or sometimes no error just quits. All other games works fine(haven't tried other EA games tho).
Reinstalled EA app twice,
Installed Battelfield 2042 twice, even on a other drive.
Removed Nvidia app and rolled back previous graphics driver.
Before that i did a couple of game related configuration in nvidia app to like go for perfomance, remove in game overlays etc.
Tried the fix above, but not luck. Instant DirectX error men trying to connect to conquest game.
Conclusion is to look into windows update, so lets see what happens. :S
