To run my react native application, I try to create & run an emulator in android studio and get this error every time.
Couldn't start project on Android: It took too long to start the Android emulator: Pixel_2_API_30. You can try starting the emulator manually from the terminal with: C:\Users\ASUS\AppData\Local\Android\Sdk/emulator/emulator @Pixel_2_API_30
You must wipe the data. For that go to Device Manager -> Wipe Data. After that restart your Android Studio. Then after your issue may be solved. Have a look on below mentioned image to get a better understanding.
