Android Studio 4.0

Hi, trying to build Amazon Fire App on Windows 10, and receiving error below:

Cannot set the value of read-only property ‘outputFile’ for ApkVariantOutputImpl_Decorated{apkData=Main{type=MAIN, fullName=debug, filters=, versionCode=10, versionName=1.0.7}} of type com.android.build.gradle.internal.api.ApkVariantOutputImpl.
