Visual Studio Code Run Options Are Not Responding For Flutter (Like Run --> Start Debugging)

As the title mention, Visual Studio Code is not responding when I follow,
Run --> Start Debugging
Run --> Run Without Debugging
After trying those ways, the IDE is not giving any reaction. No error log appears on Terminal or Debug Console
The good thing is that "flutter run" is working robustly
What have I tried for a solution?
Checked similar questions on SO
Run "flutter doctor" to check any issue (the log is below)
Checked Dart and Flutter plugins are installed on Visual Studio Code
Restarted Visual Studio Code, also PC

Finally, the following method solved the problem.
(This may have been a specific problem with my device)
Uninstalling the app on the emulator and then building it solved the problem.

flutter failed to connect android device and off application on iPhone simulator

when I call debug mode on an android device
Error connecting to the service protocol: failed to connect to http://127.0.0.1:60027/bncnE_T-mWw=/
and also asks for permission to wifi, but through a notification, if I give permission, it shows a white screen and the same error
but everything starts quietly if you build the apk and install through it
with an iPhone simulator, the application starts and immediately closes, and in the android studio it is written that the connection is taking too long, it may have crashed
