Hi, I am working on android studio project and this error keeps showing. I have synced project with gradle file but doesn’t work.

This is my --scan result.

The build scan is not too useful as it is not if the failing build.
But anyway this is not really a Gradle topic. You try to use a Kotlin 1.9 compiled library while compiling with Kotlin 1.7, this does not work.

Hi, I know it’s not a gradle topic but do you know how to solve the error? I have changed the Kotlin compiler version but still doesn’t work.

I can only guess that you did not do it correctly.
You either cannot use what was compiled with Kotlin 1.9 when compiling with 1.7, or need to compile with newer than 1.7.
