Hey there. Please check if the following steps will help in this situation.
- Use only your controller to navigate the opening screens
- If the controller works offline but not online, restart FC 26 and go through the opening screens again using the controller only
- Close the game, unplug the controller, plug it back in, then relaunch
- Try a different USB data cable and a rear USB 3.x port
- Test wired first before using Bluetooth
- Try Fullscreen and Windowed/Borderless modes
- Set a frame-rate cap such as 30 or 60 FPS
- Enable VSync
- Lower graphics settings like shadows and effects
- Run the game .exe as Administrator as a test
- Disconnect other input devices so only one controller is connected
- Turn off overlays while testing such as EA App, Steam Overlay, Xbox Game Bar, Discord, GeForce Experience, RivaTuner
