[Regression] URP Unlit ShaderGraph is broken in Hybrid Renderer V2
How to reproduce:
1. Open attached project (ECS_HybridURPSamples.zip) with 2020.3
2. Open MaterialOverridesSample scene
Expected result: Spheres that are using unlit URP shader are rendered
Actual result: The spheres using unlit URP shader graph are not rendered and errors are thrown in the console:
A Hybrid Renderer V2 batch is using the shader "Shader Graphs/URPUnlitGraph", but the shader is either not compatible with Hybrid Renderer V2, is missing the DOTS_INSTANCING_ON variant, or there is a problem with the DOTS_INSTANCING_ON variant.
Reproducible with: 10.4.0(2020.3.5f1), 11.0.0(2021.1.4f1)
Not reproducible with: 10.2.2, 10.3.2(2020.3.3f1)

Although not ideal, downgrading to 10.3.2 worked for me.
Upgrading to 10.5 didn't work.

Interestingly, a NEW shadergraph I created has the same issue now on 10.5.0 - investigating. Also, saving the graphs.

On Unity 2020.3.6f1, if you manually UPGRADE to URP 10.5.0, the issue is also no longer reproducible.
The forum thread says a fix would be in 10.6.0, so this is a bit of a (pleasant, if unsettling) surprise. You know, like when you no longer know where the Spider / Cockroach disappeared to. :)

DK_A5B, a workaround to this issue is to go into manifest.json AND packages-lock.json and replace all occurrences of URP 10.4.0 with 10.3.2 (important to do that in dependencies of other packages, as well, hence the lock file, too).
You need to re-do this after every Unity update, but it currently keeps me afloat.

This issue is particularly problematic now that DOTS-ECS is fixed to the 2020 LTS version. This means that the ECS Hybrid Renderer does not work with the most recent version of 2020 LTS (2020.3.x) and URP 10.4.0 (the most recent version of URP for 2020 LTS).
Please fix.

Actually the unlit graphs also work in one version of 11.0, and that is exclusively the version of URP that is in Unity 2021.1.0f1, in case that helps investigations.
See issues 1331111 and 1327570.
