We have a problem building our application with 0.69.0 with the following error

Class 'kotlin.Unit' was compiled with an incompatible version of Kotlin. T binary version of its metadata is 1.6.0, expected version is 1.4.0.

I suppose this PR would fix that :)

Edit:
Actually, just noticed that the Android build from this PR is failing with the same error

quick fix:

• open file node_modules/react-native-screens/android/build.gradle
• find line classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:${safeExtGet('kotlinVersion', '1.4.10')}"
• change 1.4.10 to 1.6.21
