What to do
- Check the player number light on each controller and match it to the on-screen player order.
- Disconnect all controllers, then reconnect them one at a time in the order you want them assigned.
- Reassign player slots manually in the game's controller settings if it offers that option.
- Turn off and unpair any controllers not currently being used to avoid conflicts.
- Restart the console fully to reset all active wireless pairings.
- Update the system software in case of a known multiplayer input bug.
- Test with just two controllers before adding more to isolate which pair is conflicting.
