How to fix Cloud Build using Fallback Materials only?

Hello Unity Community,

I have stumbled upon a problem when using Unity Universal Render Pipeline and Unity Cloud Build for deployment (for iOS) recently. For some reason, cloud build replaces all materials with fallback materials. However, when deploying locally using XCode everything works fine. I am using "URP / Lit" materials only.

Cloud Build Log :

 [Unity] Compiling shader "Hidden/Shader Graph/FallbackError" pass "Pass 0" (vp)
 [Unity] Compiling shader "Hidden/Universal Render Pipeline/FallbackError" pass "Pass 0" (vp)
 [Unity] Compiling shader "Hidden/Universal Render Pipeline/FallbackError" pass "Pass 0" (vp)

Did someone experience similar issues and if yes, were you able to fix them?

Thanks In Advance
