Description

App crashes just after startup if an iOS Contact exists with URL label Telegram (used for Siri intents) with URL https://t.me/@id-500[nnnn] that matches an open group chat group id. Contact must be deleted for app to stop crashing on startup. Does not happen if the ID is negative but does not match an actual open group chat id (e.g. https://t.me/@id-5005 will not cause a crash).

Expected Behavior

App should not crash even if contact with this URL format / value exists

Actual Behavior

App crashes - cannot be used at all

Steps to Reproduce

1. Open a group chat
2. Invide @getidsbot to get the [group ID] (like -50012345678)
3. Create iOS contact with URL
   a. Label: Telegram
   b. URL: https://t.me/@id-50012345678
4. Close Telegram
5. Open Telegram
6. App should crash every single time you open the app and have this group in your chat list
7. Change group id to value that does not match group id - app should no longer crash on startup
8. Delete the contact - app should no longer crash on startup
