Update all dependencies to the latest version to solve the error. Check below dependencies also try to have kotlin version:

implementation 'androidx.lifecycle:lifecycle-viewmodel-ktx:2.4.0'

Most likely, one of your dependencies uses the kotlin version of the viewmodel library whereas your code uses the java version.
