I am also getting but i solve it by using:
CameraEnabled = false;
await Shell.Current.Navigation.PopAsync(true);
I have to first disabled camera and then, do all things like back or anything. Like when i detect, i have to first off cameraenabled false and then, it does not occur

I haven't managed to replicate the issue as I'm using Shell for navigation. But if @haideralifaizi solves your problem then it is a issue with internal resource mismanagement when navigating from the page. Although it can work without it, it is a best practice to set CameraEnabled = false when closing or navigating from the page.
