my build.gradle

  ext {
    buildToolsVersion = "29.0.3"
    minSdkVersion = 21
    compileSdkVersion = 30

To solve this issue just change the compileSdkVersion in your build.gradle file.

Open android > build.gradle file. Change compileSdkVersion from 29 to 30. Change targetSdkVersion from 29 to 30. now run again.
