Man, that's an explanation! Thanks for sharing the insight of the problem, so me and everyone that will hit this post can understand and fix its own code. Thanks again Quinn

After you explained it, it makes sense. Thanks Quinn!

Hello Quinn! setMetadata(...) is set inside the @MainActor class AudioPlayerProvider: ObservableObject along AVPlayer and some @Published properties. The function itself can be called inside the action of a SwiftUI button with: Task { try? await self.audioPlayerProvider.setMetadata(title: ..., artist: ..., artwork: ...) } or inside a .onChange event triggered by a metadata ObservableObject class, when needed. So always on the thread the enclosing view runs. Thanks again

I can confirm that your workaround is working and the app is not crashing anymore. I'll check for future resolution of the problem. Thanks Quinn!

Thank you very much!

Answering my own post. This problem appears to happen on the simulator only. Using a real device shows no problem at all!
