This appears to be a recent change to Unity's Addressables package. 2.3.7 introduces a new namespace called "Editor". Since our Core SDK references this assembly, this is now a name collision between the "UnityEditor.Editor" classname and the Addressable namespace called "Editor". See this thread for more details: https://discussions.unity.com/t/addressables-2-3-7-compile-error-editor-is-a-namespace-but-is-used-like-a-type/1578531

We can change the Core SDK to eliminate this name collision in future versions (that is, apply the same change you mentioned above), but for now you'll either have to modify the Core SDK as an embedded package, or use a different version of Unity's Addressables package.

This looks like an issue importing the new package (I've seen something similar before). Could you try reimporting the script assets? From the "Project" window, navigate to Packages > Meta XR Core SDK > right click and select "Reimport".

If all else fails, try removing the Library folder.

Of course I tried these things and only workaround was to roll back to v69. But our project requires the new features in v71. The issues seems to be that the namespace is now missing in the library for the editor folder. Please fix it. I was able to fix locally but I don't like having an embedded package in project for long term. Only acceptable for temporary fixes.

Hmm, I just created a new project in 600.0.23f1, installed the v69 all-in-one package, then updated it to v71 without issue.  Could you share the following?

  1. Project manifest (Packages/manifest.json)
  2. List of scripting defines (Player Settings > Other Settings > Script Compilation)
The issues seems to be that the namespace is now missing in the library for the editor folder. Please fix it. I was able to fix locally...

What fix did you apply locally?
