I believe I am seeing this same crash with SDK v3.1.0. After updating my Swift packages I am now using TwilioTwilsockLib version 2.1.1 which has not been released as of today.

[farmer-dhi]

I was able to fix this crash by forcing TwilsockLib back to 2.0.4. Obviously not a long term solution, but it works for now until this crash is fixed in the library.

@farmer-dhi How can we force TwilsockLib back to 2.0.4. Can you please help me with the same

[farmer-dhi]

Add https://github.com/twilio/twilsock-ios as a package dependency and use "Exact Version". Set the version to 2.0.4
