I had the same problem for 3 weeks after various updates (NVIDIA drivers / windows update / BF2042) at the same time, a solution which worked for me (PC / windows 10 / EA desktop) in the compatibility options of BF2042.exe (right click / properties / compatibility), I checked the deactivation of full screen optimization... and it's back to normal.
After ten's of different solutions this stupid solution of disable fullscreen optimization actually worked! Thank you.
I just wanted to say, thank you from the bottom of my heart.
I've been having the issue described in the title not just with BF2042, but with literally every EA title that uses the new EA anticheat software. Was convinced the software itself was the problem, and so was EA support when I tried (unsuccessfully) to get their help fixing it.
No other solution I found online worked. Literally, I tried everything that comes up if you google for how to fix this. But your solution did - I haven't been able to play for months, and now I can. I haven't tried it on my other games yet, but I figure if it's working for one it'll work for all.
