Solution

1 change the path in:”C:\Users\USERNAME\StudioProjects\ProjectName\android\gradle\wrapper\gradle-wrapper.properties”

change the last line to : distributionUrl=https\://services.gradle.org/distributions/gradle-7.1.2-all.zip

2 change the build.gradle dependencies

{
classpath ‘com.android.tools.build:gradle:7.1.2’
classpath “org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version”
}

7.1.2 is just the sample.
