Unity window is freezed when after pressing 'Attack to unity' button in Visual studio.,Unity window is freezed when pressing 'Attach to Unity', so I am not able to debug...

Unable to debug because you cannot return to Unity after pressing the 'Attach to Unity' button. I can't even switch windows to Unity after pressing the button. Pressing the button causes to lock Unity. I can't even switch windows to Unity. To return to Unity, I have to release 'Attach to Unity' mode
