The only way I've found to make it work again, is to restart the device. After that it starts getting called.

I don't think it's related to this. The link you've posted talks about the problem many developers have had with NSData's description property which changed since iOS 13. This thread is addresses the issue that very often, when building with debug config from xcode at least, application's delegate methods that inform us whether the APNs token was generated successfully or not, do not get called at all. And yes, if you restart the device it starts working again only to stop after an unknown period of time.Hope somebody from Apple responds to this thread and informs us wether this is a bug they'll fix soon or maybe intended functionality for debug apps.
