Materials showing up pink & black in google play builds

Hello everyone, I'm pretty new to developing for mobile but I've run into this weird issue I can't seem to find anywhere online. I've built and tested everything fine for iOS but whenever I load up my game on android the entire 3d environment is black and the player is pink, all of the UI is fine.

Some things I've tried already:

• Adding more Shaders to 'Always Included Shaders'
• Swapping Instancing Variants in Shader Stripping from Strip Unused to Keep All
• Color Space in Project Settings > Player > Other set to Gamma, Auto Graphics API ticked, Multithreaded Rendering turned off
• Removing all third-party shader assets & changing used materials
• Changing to all 'Texture Compression' types in Build Settings
• Changing the 'Compression Method' in Build Settings

I have no idea why this is happening, any help would be much appreciated.

 

for anyone stumbling upon this I found that the issue was with Post Processing, after disabling all of it everything worked fine.
