NOTE : even Android studio displays such error , both of Android studio and VS code don't connect to the emulator properly (Pixel XL API 30)

Answer 1

I was also facing the same problem in vs code. instead of clicking "run the project" in vs code i clicked "start debugging" and it woreked for me.

Answer 2

I was getting the same error when I try to run it from the run button at the top right corner

But I notice there are three options above the main method there are three options I selected Debug and it successfully worked!
