Hey there @scopxtech! Welcome to the community! Looks like something is going wrong with a shader’s processing. Back up your project safely (as standard practice as this operation is supposed to be safe). Head into your project folder and delete the DerivedDataCache and any Builds folder. This will delete your cached shaders and force a rebuild of them, this won’t help the build but if the rebuild fails you may get a warning to which shader couldn’t compile. This error can often stem from trying to build over a previous build, or if some shaders are corrupted.
