[macOS] Editor crashes when trying to access audio capture devices

MacOS

-

Reproduction steps:
1. Open user attached project
2. Open Scene "MiniCam" (Assets/NatDevice/Examples/MiniCam)
3. Audio capture devices are being accessed in MediaDeviceQuery.cs (95; 102)
4. Open MediaDeviceQuery.cs (note 1) on line 57Comment out devices.AddRange(WebCamDevices())
5. Enter Play Mode
6. Don't allow a microphone access
===Crash occurs===

Reproducible with: 2019.1.0a10, 2019.2.21, 2019.3.8f1, 2020.1.0b5, 2020.2.0a7

Not reproducible with: 2019.1.0a1

Not sure if this regression or not, I cloud not reproduce the crash with 2019.1.0a1 once, but after that testing higher versions when Unity asks developers tools access and Unity is added to the privacy setting, after that, it crashes all the time.
Regression might be in 2019.1.0a1-2019.1.0a10

IMPORTANT: when testing NEVER Allow Unity to access the microphone or you will not be able to use that device for testing anymore. If Unity asked for microphone permission it means that the issue did not reproduce (in that case just turn off the window).

Notes:
- Step 4 is needed because accessing Cameras also causes a crash due to the absence of permission request, and this is a known issue
- If in earlier versions you allowed Unity to access microphone at least once, it will not crash anymore, and resetting default permissions for microphone makes Unity always crash
- When attempting to enter Play mode in 2018.4.20f1, Unity asks for permission to access developer tools (iirc) and, after providing the computer password, Unity freezes, but does not crash. Unity did not ask to access the microphone, either

    Resolution Note:

    This issue is caused by a crash in this plugin https://assetstore.unity.com/packages/tools/integration/natdevice-media-device-api-162053 which the author has recently fixed several of. I would recommend posting on this forum thread https://forum.unity.com/threads/natdevice-media-device-api.374690/ as there is a current known crash the author has reported to Apple.
