Loading Devices Greyed out (Android Studio) Testing An App on a physical Device

I am very new to Flutter, my issue is as follows:

After enabling USB debugging on my android phone and establishing a connection with my PC in order to deploy a simple app on a physical device, when I needed to select my phone in Android studio, I noticed that "Loading Devices" is greyed out.

How can I fix this? I need to select my phone in Android studio.


Solution 1:

i spent a full day trying to solve this issue finally I located and deleted my SDK folder then downloaded new sdk platforms and tools via SDK manager everything is working fine now
