FC26 Keyboard Issue

I started having a weird keyboard issue last week while playing FC26 on PC.In online modes, my keyboard controls are completely messed up:

• The player keeps sprinting and stopping on its own, even though I’m only using the arrow keys
• Only one key seems to work (pass), but it randomly acts as shoot, pass, or lob depending on the situation

What’s strange is that everything works perfectly fine in offline matches — the problem only happens online (Clubs, UT)

I even had a friend log into my account from a different PC, and the same issue happened there too.

Has anyone else experienced this or knows how to fix it?
