Conflict with Beautify & Postprocessor

Implementing addressables to my existing project I get an editor error about some resources from Beatify and Postprocessor package.
Here is some related to Beautify

Code (CSharp):

1. ArgumentException: An item with the same key has already been added. Key: Particles/ParticleBlendZBuffer
2. System.Collections.Generic.Dictionary`2[TKey,TValue].TryInsert (TKey key, TValue value, System.Collections.Generic.InsertionBehavior behavior) (at <f826c2584fc94ec19a48a6576640bdc5>:0)

Checked the project - there is only 1 ParticleBlendZBuffer.mat and ParticleBlendZBuffer.shader in a project.
Removing it (just for tests) cause errors related to another resources and so on. Same with PostProcessor, but here reimporting the package helped.

What could the issue? These errors appears on "Preview" or building the app.

 

Reimporting didn't help as well.. Have no clue how to fix it.

Just tested on clean project with Beautify + Addressables, and got this error or preview/build

Code (CSharp):

1. ArgumentException: An element with the same key already exists in the dictionary.

UPDATED

Found a solution - renamed shaders, because there was same naming for some different types of files, but seems Addressables got some bug with it.
Example:
Beautify/Resources/Shaders/BeautifyBasic.shader and Beautify/Resources/Shaders/BeautifyBasic.cginc
or
Beautify/Resources/Particles/ParticleBlendZBuffer.shader and Beautify/Resources/Particles/ParticleBlendZBuffer.mat

 

Thanks for reaching out. Items in Resources are automatically given an address that matches what their Resources.Load lookup is. This is the filename without extension. Your example causes two items to have the same lookup key.
We have a fix coming for this within the next release or two.
Thanks,
Bill
