2. Install the script as per the home page's instructions for Chrome

3. Log in to Xbox Cloud gaming

4. Enable emulated MKB

5. Launch any game and enable the developer console
   6.Press F8 to toggle controller on and off

Test this: https://github.com/redphx/better-xcloud/raw/refs/heads/typescript/dist/better-xcloud.user.js

If it still happens, show me the error in the Chrome devtools

I did try the one you linked and in the dev console, it's the same lines about an uncaught promise.

Am I looking in the right area or which tab should I be checking on Brave's dev tools?
