Resolution Note:
This is a mixture of changes to RPs breaking existing assumptions for SG that allowed our generated shaders to coincidentally work with Canvas/UI. The real issue is that we do not have an officially supported target or provided clear workflows for supporting it yet. We have to treat this as a feature request. Roadmap for official support is here: https://portal.productboard.com/unity/1-unity-platform-rendering-visual-effects/c/50-ui-integration-with-shader-graph). While some versions happened to function with SG materials in the canvas, it has not ever been given official support.
