Cannot use AVAudioPlayer in simulator in Xcode 12 beta 3

This might relate to a similar problem I had with the first beta, where trying to use an AVAudioPlayer caused the app to hang and spit out a lot of errors and not really work. This was resolved in beta 2 but beta 3 has reverted back to the old behaviour where trying to call prepareToPlay() or play() on a valid AVAudioPlayer instance causes lots of error output (and no sound).

Additionally, trying to call prepareToPlay() during an onAppear{ } block for the root view of a SwiftUI app appears to block the main thread while all of this error output is being spat out and causes a significant delay in app launch.

I've been able to reproduce this bug in a very simple example app. I have filed a feedback: FB8116155

This is an example of the sort of errors I'm getting:

Is anyone else able to reproduce this or having similar problems?

I can also confirm that this is still there in Beta 4. Audioplayer init causes these errors in the simulator.

Still a problem in beta 5, albeit with less verbose error output:

Why is this still a problem. We recently tried to migrate our build machines to an m1 Mac mini and run into the exact problem with the sims. Its absolutely mind boggling that this issue is still around and there is ZERO acknowledgment from apple side. For us we had to disable all sounds / videos using AVFoundation to get our tests to run, which absolutely unacceptable.
