You may want to try plugging the keyboard into a different USB port on the Xbox One and see if still crashes when using the paste shortcut. Do you have a second keyboard you could test the paste shortcut on? Power-cycling the console and re-installing could also help resolve the crash.
Power cycle an Xbox One:
- Turn off the console by holding the [Xbox button] on the front of the console for approximately 10 seconds. The console will power down.
- Disconnect the power cable from the back of the console. After 30 seconds reconnect the power cable to the back of the console.
- Turn the console back on by pressing the [Xbox button] on the console or the [Xbox button] on the controller
