Snack, code example, screenshot, or link to a repository

buildscript {

dependencies {
    classpath Gradle.agp <---- 7.0.3
    classpath "com.facebook.react:react-native-gradle-plugin"

Can you re-run your Gradle build with --scan and send over the Gradle Scan?
I believe there is somethign else in your project which is overriding the Kotlin version somehow.

I have the same problem scans.gradle.com/s/acl2xejf3ctj6

From the Gradle scan, it seems like you have Kotlin 1.7.20 inside your build.gradle.kts file. Could you share it?

as i know，kotlin 1.7 has more strict rules than the versions below，but… why not add the ExperimentalStdApi to the warnning Task to avoid the problem🥹

[cortinico]

I've investigate this issue, and the root cause seems to be your Gradle version.
Moving to Gradle 7.6 should fix this issue.

Also I've updated RNGP to use code that is compatible down to Kotlin 1.5 (and tested also with 1.4) so this warning will go away:

/node_modules/react-native-gradle-plugin/src/main/kotlin/com/facebook/react/tasks/BundleHermesCTask.kt: (138, 11): This declaration is experimental and its usage must be marked with '@kotlin.ExperimentalStdlibApi' or '@OptIn(kotlin.ExperimentalStdlibApi::class)'

For those having this issue when building their react native apps using Expo's EAS service, I deleted my entire Android folder in my project and when I tried eas build again the build was completed successfully.
I hope someone will find this helpful. This gave me a hardddd time.
