I had the same issue, I fixed this by changing some lines in build.gradle files. I came to this solution from https://kotlinlang.org/docs/reference/using-gradle.html project level build.gradle:

//this has to do with kotlin androidX support, Kotlin supports androidX from version 1.3.x //change this line //ext.kotlin_version = '1.2.31' //to ext.kotlin_version = '1.3.30'

app level build.gradle: //Change this line //implementation "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version" //to implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"

Hope it helps you too.

I solved it by upgrading my gradle dependency in the android/build.gradle file: classpath 'com.android.tools.build:gradle:3.3.1' (I was previously on version 3.2.1)
