If this is set to 20 or lower, you need to configure your app for multiDex support.
defaultConfig {
applicationId "com.inspire.aaym"
minSdkVersion 21
targetSdkVersion 30
}
So, if your app is not intended to be used in the Android version prior to 5.0, setting the minSdkVersion number to 21 will easily fix this issue.
