When I try to connect the app to my device using bluetooth I get an error saying: Gatt Callback error 4, I didn't make any code adjustements.

Try connect to your device using OS first. Maybe some pairing issues.

Also make sure you granted all permissions.

As you are not able to connect the issue happened in MainViewModel: adapter.Connect method. In sample I use Plugin.BLE package. It is still in preview for MAUI. Maybe there is a known issue.
