the @JvmInline annotation on my value class gives me

This declaration is only available since Kotlin 1.5 and cannot be used with the specified API version 1.4

even though in my build.gradle.kts i have kotlin("jvm") version "1.5.21"
whats wrong here?

Do you get this error in project files, or in the Gradle build kts file itself? If the latter, gradle's DSL still is at Kotlin 1.4 I believe. If the former, maybe you have another language level override somewhere in the build file?

If you use Jetpack Compose, make sure to set kotlinCompilerVersion and kotlinCompilerExtensionVersion. (not sure the name)
