Type androidx.appcompat.resources.R$dimen is defined multiple times

Question

We have a React Native app where after upgrading to Android Studio 3.6.1 and Gradle plugin 3.6.1 we are seeing this compilation error:

Type androidx.appcompat.resources.R$dimen is defined multiple times: /Users/andrew/Software/project/android/app/build/intermediates/project_dex_archive/productionRelease/out/androidx/appcompat/resources/R$dimen.dex, /Users/andrew/Software/project/android/app/build/intermediates/project_dex_archive/productionRelease/out/15bdf8225afad69777cd7f9bd328ab094900c8289014e0107b56c5c62099dfea_3.jar:classes.dex 

Here are our dependencies:

Can anyone help figure out what the issue is, and how could we debug this type of issue in the future? Thank you!

Got the same problem, just clean project and rebuild again.
