A. 1. Update the app: Go to the App Store and check for any available updates for CollX. Developers often release updates to fix bugs that cause crashes. 2. Free up storage space: Go to Settings > General > iPhone Storage and check if you have enough free space. If storage is low, delete unused apps or media files. 3. Reset settings: Go to Settings > General > Reset > Reset All Settings. This won’t delete your data but will reset system settings, which may resolve conflicts causing crashes.

B. 4. Check for iOS updates: Go to Settings > General > Software Update and ensure your iPhone is running the latest version of iOS.
