A. 1. Update the app: Open the App Store, tap on your profile icon, and check for updates for Haylou Fun. Installing the latest version can fix bugs that cause crashes. 2. Free up storage space: Go to Settings > General > iPhone Storage and check how much space is available. If storage is low, delete unused apps or files to create more space.

B. 3. Reset settings: Go to Settings > General > Reset > Reset All Settings. This will not delete your data but will reset system settings which might resolve conflicts causing crashes.
