The fix for #506 in b997561 hardcoded the org.gradle.kotlin.dsl.provideDelegate import but provideDelegate operator functions aren't limited to org.gradle.kotlin.dsl and could be present in any Kotlin library.

See https://kotlinlang.org/docs/reference/delegated-properties.html#providing-a-delegate-since-11

The fix should be extended to any import of a provideDelegate operator function.
