*How to reproduce*
* Create a vfxg from the Starter Template (Simple loop)
* Right Click and select Convert Output
* Choose a ShaderGraph Quad output
* Create an simple ShaderGraph
* Make sure to enable VFX Graph Support.
* Create a HLSL block in this Output Context
* !image-2023-11-27-14-38-52-209.png|width=195,height=342!

*Alternative Reproduction Step:*
-Import the Attached Package
-Open the new VFX.vfx
-Notice that you should have errors in the console
-Disable the hlsl block in the output context and compile the vfx

-Notice that this time the vfx compile without issue.

*Expected Result:*
We should see our VFX and we should have the ability to use the HSLS default block to offset the particles Position.

*Actual Result:*
With a ShaderGraph Output and HLSL Block inside it, the VFX doesn't compile anymore and throw errors in the Console.

Note, If your Sytem have two outputs both with an HLSL Block and that one is a regular Output and the other is an ShaderGraph output. No compilation errors will be thrwon in the console. But Only the regular output will draw particles and the Shadergraph Output still won't work.
