“Exception: AddressableAssetSettings not found" error is thrown in the Console when creating an ImprovedNamesOutputRule Asset

Steps to reproduce:
1. Create new Unity project using Universal 3D Template
2. Open Package Manager window
3. Find and install Addressables package
4. In Project window create New Improved Names Output Rule.Asset (Right-click in Project window > Create > Addressables > Auto Group Generator > Rules > Output Rules > ImprovedNamesOutputRule)
5. Once created, observe the Console window

Actual results: “[Worker0] Exception: AddressableAssetSettings not found. Ensure Addressables are initialized.” Error is thrown in the Console window

Expected results: No errors are thrown in the Console window, ImprovedNamesOutputRule asset menu item is hidden/disabled until Addressables are initialized/created
