Help/Support Rendering issue with After Dark?

[Aaron4174 0 iPhone 7 11.1.1]

Hi everyone, I installed After Dark through downloading the IPA and installing it through Sideloadly. 
 

But, from when I play the game, the rendering on the game is.. incomplete or broken? Most of the image on the screen is a pink pixelation, it’s playable, but objects such as trees and rocks etc and somewhat invisible, but the player will keep perform actions (e.g. chopping wood) https://ibb.co/rfBdWS8.

if this has been asked before, I apologise, I didn’t know what to ask.
