Mouse & Keyboard Become Unresponsive When Controller Is Connected (PC/Steam)

Hello Apex Legends team,

I'm experiencing an issue that started about a week ago. Whenever I plug in my controller while Apex Legends is running, my mouse and keyboard stop working in-game immediately.

I can still move my mouse cursor, but I can't click anything or type using my keyboard. However, if I Alt + Tab to another application, both my mouse and keyboard work normally. The problem only occurs when Apex Legends is the active window.

I don't remember having this issue before, so it seems like something changed recently. This has been quite frustrating because I'm unable to type in chat or communicate with my teammates during matches.

I can still use both my mouse/keyboard and controller simultaneously in other games, so the issue appears to be specific to Apex Legends. the issue occurs as soon as I connect my controller while Apex Legends is running. Even though I can move the mouse cursor in-game, I can't click on anything, and none of my keyboard inputs are recognized until I leave the game window.

Is this a known issue or bug? If there's a workaround or if there's any additional information I can provide to help reproduce the problem, I'd be happy to assist.

Thank you for your time and support.
