App keep crashing

[NoisyNicy]

You know the app used for customising your wallpaper and more, specifically about the lock screen. So, I was trying to edit my lockscreen to match the theme of my phone, then when I pressed on the side apps, the app used for customising stops, it's been a while since this happened. It's really annoying, and I don't know what to do since there's no update of the app.

I tried to troubleshoot the app like clear cache, erase data, and rebooting my phone.

Is your phone updated to the latest software/security patch? If yes, you can try the Repair Apps option in the Recovery Menu. If that still doesn't work I recommend to send feedback.
