mouse/keyboard freezing while gaming on xbox

The Xbox can't be controlled by keyboard and mouse through the Stream mode at all. While it's possible in the Minecraft Bedrock Edition to use Keyboard and mouse, all other games don't accept keyboard and mouse input at all.

You might have to try Minecraft, if you can control it via Keyboard and mouse while streaming to your PC.

Keyboard and mouse.arent offically sanctioned controllers you should know that there will.always be issues when you are trying to.circumvent the system

I understand.

Does this issue started to happen as soon as you installed these games or you were able to play them just fine for a while then they started freezing when using your mouse and keyboard?

For the following to work you must make the menu selections using your keyboard. If you use the controller to make your menu selections to start the game you will be placed in a room for those with a controller and your keyboard/mouse will be non functional
to make it fair to other players. To enter the room for keyboard and mouse users the game must be started by selecting the options using the keyboard/mouse. Hope this helps.

Mouse and keyboard support

Fortnite on Xbox One supports the ability to play with a mouse and keyboard. Note that when using a mouse and keyboard on Xbox One, you’ll be placed in a game with other users who also chose mouse and keyboard as their control option. To enable your setup
to use mouse and keyboard, see Mouse and Keyboard Support

Note If you’re on a child account, you’ll also need to enable settings for cross-network play to use a keyboard and mouse while playing
on Xbox One.

Mouse freeze, keyboard still working, but if I disconnect the mouse, keyboard and controller from USB and try to connect again, not works.
