Canceling Screen Sharing Selection Results in 'Permission Denied' Message

### Description of the bug:

I ran the project to display the screen and started testing by pressing the streaming button.
When I clicked the screen sharing button, a modal appeared where I could select the programs I was running. At that point, I attempted to exit the selection modal without choosing any program by pressing ESC or the cancel button. After doing so, a screen with a message like "Permission Denied" appeared.

### Actual vs expected behavior:

+ Expected
Noting. Just close modal.

+ Actual
Permission Denied.

### Any other information you'd like to share?

While this is not a functional issue, it seems evident that it could negatively impact the user experience.
