I have this problem since I started playing Minecraft bedrock edition. The problem is when I am in any Minecraft world and I press Win+G to open Xbox Game Bar, the app becomes very laggy. This only occures while I am in a Minecraft world. The app works normal when I am in the main menu (not in a Minecraft world). But when I am in one it is almost impossible to use Xbox game bar. It is even hard to get out of the app and get back into Minecraft, because of the lag.

Steps to reproduce the issue.
1. Go into Minecraft (Bedrock)
2. Open up any world
3. Press Win+G to open Xbox Game bar
4. Try to do something in Xbox game bar
5. LAG
