[Issue] mobile sprites

So having an issue with my game when it comes to mobile.
Everything works perfectly on the PC version though when doing quick testing,

The issue is some of my sprites won't render they show up as white squares.
They were working but I have not changed the settings on the image at all so I have no idea why they suddenly stopped working on the mobile version.
Sprite Sheet
512x512 sprite sheet with 64x64 sprites.

Edit 1:
Only thing I could find was change it to point no filter, but that didn't work either.

Edit 2:
So seems to be how I load my items just is not allowing for the sprites to be loaded. I changed to a sprite sheet that is working and even that wont render my items, however it'll render the sheet if it is not using my item system.

 

Check the size of the sprites and supported texture size for your devices. If your sprites take 4k pixels or more, they may not be supported on certain devices.
