I am new to React native and using Visual Studio Code for Development. All of a Sudden I am getting error while running the Application (npm run android). Its saying the "Failed to launch Emulator" but still I could see emulator up and running. I have copied full data that I get below. Please guide me how I can resolve the same.

some steps may help you:
before run react-native project
cd C:\Users\30103061\AppData\Local\Android\Sdk\emulator
emulator.exe @Pixel_6_API_30SS
adb devices # you should see Pixel_6_API_30SS is active
npm start -- --reset-cache
npx react-native run-android
if not work another way is to remove your emulator and install another one.
