Doing a clean of the project fixed a similar problem for me; it might work for you, too. Here is the error that I had:

Seems you have at dependencies different versions of play-services-base library and library which depends of it, for ex in my case it was due to
implementation "com.google.android.gms:play-services-base:17.0.0"
and
implementation "com.google.firebase:firebase-messaging:20.1.0"
and at top gradle file I had this:
allprojects {
configurations.all {
resolutionStrategy {
failOnVersionConflict()
force "com.google.android.gms:play-services-base:17.0.0"
}
}
}
to fix it I just changed ver of play-services-base at top-level gradle file
...
force "com.google.android.gms:play-services-base:17.1.0"
...
