“Unsupported class file major version 63” means you use Java 19 to run Gradle.
The path one line above it shows you are using Gradle 7.5.
Now have a look at Compatibility Matrix :slight_smile:

If you are using Android Studio:

  • click on Android Studio,
  • click on “Build” in menu nav,
  • click on “Clean Project”.
    ^This resolved the issue for me.
