$ ionic capacitor run android -l is works but doesn't runs android device

Hello everyone I am mobile app developer with capacitor ionic. When I was started develop an app I run $ ionic capacitor run android -l for live reload. Everything was fine until I forgot an unused variable on my code. Unused variable blocked run android virtual device. I mean server starting and I can open app in my browser but android virtual device never ran. I deleted unused variable and problem fixed. Maybe this solution helps if you have this problem.
