Is there a way to get the resolvedType of an annotation argument? I'm using this in FirDeclarationGenerationExtension to create a function with a specific returnType:

val annotation = resolvedAnnotationsWithArguments.getAnnotationByClassId(annotationClassId, session) ?: return null
val returnTypeArgument = annotation.findArgumentByName(returnTypeArg, false) as? FirGetClassCall
val returnType = returnTypeArgument?.resolvedType

The annotation is like: @Generate(returnType = MyClass::class). If the value is present, then the return type will be the specified, or the type of the class otherwise.

But Caused by: org.jetbrains.kotlin.utils.exceptions.KotlinIllegalArgumentExceptionWithAttachments: Expected expression 'FirGetClassCallImpl' to be resolved is thrown.

FirDeclarationGenerationExtension could be called before the arguments of annotation are resolved, so the answer is no for the general case

And is there a way to modify the return type after the function is generated? Like FirStatusTransformerExtension?

No
