Mario Kart World Joycon issues

I just got my switch 2 today, and everything is working great, but for whatever reason, in docked mario kart world specifically, my joycons start to break. They start rumbling really slowly and get a ton of input delay along with dropping inputs before disconnecting. When going back to the home screen, the controller issues persist, until I close out of MK world, and then everything goes back to normal. Any help on how to fix this would be greatly appreciated!
