Actual results: Unity Editor crashes

Notes:
- This crash is reproducible only on macOS - on Windows and Linux, Unity Editor does not crash
- "You Are Currently Offline" message is thrown on all machines - Windows, macOS, and Linux
- For some reason "You Are Currently Offline" message is thrown only for this Asset
- Unity Editor throws this message on all versions - from 2017.4 to the 2020.1
- Inspecting other Assets with Soundcloud link does not produce "You Are Currently Offline" message and does not crash
- If you open this Asset in browser and press Soundcloud link, it would be successfully opened and you can listen the sound
- Images for Reference and Stack Trace are attached in Comments section
