LinkedIn app for iOS: App crashes frequently when deleting Arabic characters

iOS 13.1.1
LinkedIn app for iOS (version 9.1.148)

Description:

The LinkedIn app for iOS (version 9.1.148) frequently crashes after the user enters in Arabic characters into a post box, and then deletes them.

This problem was first mentioned, here:

@LinkedInHelp it’s very difficult to report a bug in LinkedIn, every time I paste an Arabic article into IOS LinkedIn app it crashes, I tried to report it through the app but couldn’t and my only solution was to do it via the browser,@LinkedIn @LinkedInImpact @LinkedInEditors

This is easier to show than it is to describe.


Steps to Reproduce:

1. Launch the LinkedIn app for iOS (version 9.1.148)
2. (signed into an account) paste Arabic characters into a status update box
3. Slowly begin deleting the Arabic text

Result: Slowly deleting Arabic text inside of an status update will eventually crash the LinkedIn app


Expected: Deleting Arabic text shouldn't crash the LinkedIn app 

Copy some Arabic text....

Paste in the Arabic text....

Slowly begin deleting the text...

Here is the crash.
