4.13.0 preview 3 packaging - Could not find a native player for file [...]

Have you moved the OpenSource() line from your constructor into a function such as BeginPlay()?

If you do this it should resolve the error that you’re seeing.

I have the same issue. Any news on this?

Hey Ale_32,

Have you tried moving the OpenSource() line into BeginPlay() (if it isn’t already) as I suggested to orkenstein?

If so, could you please provide the full code that you are using so that I can attempt to reproduce the issue on my end? I’m currently not experiencing the same behavior.
