[Possible Bug?] Hey! Was messing around with Swift Export and found a really unusual behavior regarding enum classes. More info under this message :slightly_smiling_face:

If I have a class like this:

```class Greeting {

    fun test(): String = "Test"
    fun type(): GreetingType = GreetingType.whats_UP
}

enum class GreetingType {
    HI,
    hello,
    whats_UP,
    Hey;
}```
And try to fetch a `GreetingType` by calling `type()`, the app crashes. It doesn't matter what enum class value I'm returning, the crash always happens. `__externalRCRefUnsafe` in the generated `Shared.swift` file has a memory address that does not represent any of the memory addresses for the other enum class values, throwing a `fatalError()` (check screenshot)

If I initialize a variable directly by referencing a enum class value then the crash doesn't happen: `val a = <http://org.example.com|org.example.com>.GreetingType.HI`

This only happens when I try to get the value from a function.

I created a really small repro using KMP Wizard, <https://github.com/DanielSouzaBertoldi/swift-export-enum-repro|here's the link>.

Am I missing something here? I'm not sure if there's an actual bug or I'm just doing something silly which in turn causes the bug.

Yes, hi :slightly_smiling_face:  Thanks for the report
This is a known bug - <https://youtrack.jetbrains.com/issue/KT-83730>

Fix is already on the review and should be released with 2.4.0 :slightly_smiling_face:
