Based on the crash dump, I suspect that it could be a problem with a service called Tookan from a company called JungleWorks.

Here's the crash dump. From the dump, you can see it's pointing to this mysterious Tookan as the culprit:

Steps to Reproduce:

1. Download and launch the Port Supply Co. app for iOS
2. Select the side bar in upper left
3. Select "Guest User"
4. Select "Sign Up"
5. On the "Sign Up to Continue!" page press the phone drop down

Result: The Port Supply Co. app crashes if the user selects the phone drop down - crash dump mentions Tookan Vendor

Expected: That the Port Supply Co. app will not crash if the user selects the phone drop down

App crashes after the user taps on this option...
