Hello Brettzels A,
Welcome to Microsoft Q&A forum.
That is a weird behavior of the Game Bar. I'm not sure what happened yet, but it might have something to do with the settings.
Before we proceed further, can you please try to reset the Xbox Game Bar first to see if it helps.
- Go to Settings > System > System components
- Select the three dots next to the Xbox Game Bar > Advanced Settings.
- Select "Reset".
