I am also getting this issue as well. Attached my stack trace below: OS Version: iOS 14.3 (18C66) Report Version: 104 Exception Type: EXC_BAD_ACCESS (SIGBUS) Exception Codes: BUS_NOOP at 0x000000011a400000 Crashed Thread: 37 Application Specific Information: appendBytes:length: > appendData: > containsString: > countByEnumeratingWithState:objects:count: > dataUsingEncoding: > JBOs > path > Attempted to dereference garbage pointer 0x11a400000.

I see that a lot of you are saying this happens only on certain voices. I only use one voice which is com.apple.speech.voice.Alex. And this crash occurs randomly (sometimes it works, sometimes it doesn't) in no particular cadence.

Actually, I marked this as answered but looking more closely at that thread... It seems to be talking about a different problem where that issue happens for CERTAIN voices, and my issue happens randomly with the voice I am using com.apple.speech.voice.Alex

I still see this prompt, 3 years later... This bug should really be fixed, because it's confusing as hell.
