If I set the compiler version to 1.4.20 (intead of 1.4.10)

composeOptions {
  kotlinCompilerVersion = "1.4.20"
  kotlinCompilerExtensionVersion = "1.0.0-alpha07"
}

I get this error:

> Task :androidApp:compileDebugKotlin FAILED
w: ATTENTION!
This build uses unsafe internal compiler arguments:

-XXLanguage:+NonParenthesizedAnnotationsOnFunctionalTypes

This mode is not recommended for production use,
as no stability/compatibility guarantees are given on
compiler or generated code. Use it at your own risk!

e: java.lang.IncompatibleClassChangeError: Found class org.jetbrains.kotlin.ir.declarations.IrClass, but interface was expected
	at androidx.compose.compiler.plugins.kotlin.VersionChecker.check(VersionChecker.kt:64)

is there a fix for this? or is Compose not compatible with 1.4.20 yet ?
