TextToSpeech crash on iOS 14.2+

Hello everyone,
I face issue with TextToSpeech in my App after iOS 14.2. When I start a player I see crash: com.apple.TextToSpeech.SpeechThread (114): EXCBADACCESS (code=1, address=0x7ffdfe300000)
This I see in Xcode:




There is report from Crashlytics:




com.apple.TextToSpeech.SpeechThread

I tried to find issues in my code, but nothing was found. I used Address Sanitiser, Thread Sanitiser, Zombie objects.

Maybe, something was changed in this API and I missed it?

I'd really appreciate it, If somebody could help me find solution.
