Crashed if recreatePlayer before call player.play()

[newbdez33]

This happened sometimes. I'm playing bunch of episodes. it crashes sometimes if we call recreatePlayer before playing next.

self.player.stop()
self.recreatePlayer()
self.player.play(url: url)

bug demo repo:

https://github.com/newbdez33/AudioStreamingBug/tree/render-crash

Tested main branch in iOS 14.2 Simulator and iPhone 7. (Xcode 12.2 and Xcode 12.3)
