How to set Kotlin version

Hello I'm facing the following error when building the android portion of https://github.com/jitsi/jitsi-meet

'let((T) -> R): R' is only available since Kotlin 1.3.50 and cannot be used in Kotlin 1.3

on line https://github.com/software-mansion/react-native-screens/blob/6c87d7749ec62fbb51fb4ec50af1fa8733ebae86/android/src/main/java/com/swmansion/rnscreens/Screen.kt#L156

In Android Studio settings shows using Kotlin 1.6 in the compiler settings and when I set a project variable kotlinVersion in build.gradle to 1.6.10 I still get the same error.
