Sorry for my previous rushed answer, hadn't read you don't have discord installed.
Well, try disabling Origin ingame, as it's another gaming overlay that might cause some issues.
If this don't help please let me know.
I disabled origin in-game, and tried loading bf2 up without peripherals. Same issue. Any ideas?
Both? Well, then the last resorts are repairing the game on origin and if that doesnt help, then reinstalling.
Have you tried another Mouse? Never heard of this solving anything but it won't hurt to try.
