Opening my emby server login page on fresh Windows 11 install in firefox immediately crashes firefox

[rsvg 18]

This is a new build, so I thought I'd log into Emby for the hell of it. The login page loads (all the js files) and then immediately disappears. I thought it was very odd. I had to do a screen recording to see if I could see an error. Nothing. The tab just closes. Yes I cleared cache, even though it's a fresh computer. 

I did a google and it said: Your Firefox crash is likely caused by a conflict with your computer's gaming controller, steering wheel, or joystick. Firefox's Gamepad API occasionally crashes when scanning for active USB controllers. The Emby login page actively polls for these devices.

Why is emby polling for controllers? I confirmed by unplugging it and now the login page loads. 

Is there some kind of controller support I can disable? This is a horrible user experience. I can't just email everyone and be like "don't use a controller and firefox in windows".
