iPhone 7 crashes when I try to install any add-on

Hello, thank you for reading me. I have Kodi 16.1 installed on my iPhone 7 (non-jailbroken) using Cydia Impactor.

I have many add-ons installed, and now it crashes every time I try to install any new add-on. I can’t say what add-on was the last one I installed since after I installed Kodi, I restored from a backup using Backup program in Kodi on the iPhone.

Any idea? Thank you.
