This also happened on Xbox Platforms, turns out this was caused by the kinect causing unintentional communication with the game.
Now, obviously you're playing on a PC platform but maybe you can try to see if there is anything plugged or connected to your PC that might interfere with your game (Background program, controller...)
If ever you can, try using another keyboard. I really don't think this is the issue here but you can also update the keyboard driver:
- Press Windows key + X, select device manager
- Locate your Keyboard device, right click and select properties
- Click on the drivers tab and select update driver.
Finally, try repairing your game in Origin. To use Repair Install for your game:
- Go to My Games in Origin
- Right-click the game image
- Select "Repair Install"
