App crashes after install before launching. My interface is public, and I I've been getting this issue since yesterday only. Nothing specific about gradle or dependency versions have changed in my project and I'm unable to get to the root cause of this. Below is the state of my dependencies:

    testImplementation 'org.mockito:mockito-android:3.1.0'
    testImplementation('com.nhaarman.mockitokotlin2:mockito-kotlin:2.2.0') {
        exclude group: 'org.jetbrains.kotlin', module: 'kotlin-stdlib'
        exclude group: 'org.jetbrains.kotlin', module: 'kotlin-reflect'
    }

You can't use inline-mock-maker in Instrumentation Tests.
