    I get this problem on 2.2.2. A workaround is to close all scenes and have an empty scene with no cameras. Also close the scene and game tabs. Then build addressables.

    For me the issue has something to do with URP post processing stack. I can also avoid this problem by turning off post processing and removing all render features. I suspect the issue is caused by SSAO.

    This does happen on 1.19.19, which I believe is the latest if you're unity 2021 LTS. The issue is related to this line:

    if (loc.IsFolder && loc.SubAssets.Count > 0)

    It's inside SetAssetEntriesBundleFileIdToCatalogEntryBundleFileId line 593 in 1.19.19. The problem is that loc.SubAssets is not guaranteed to not be null. You can check https://discussions.unity.com/t/in-75879-random-failures-when-building-addressables/946651/6 for more discussion on this, but this bug is still in.

    Overall it would be nice if even if there's no time to fix issues at least give us error messages which can help us track down what's wrong.
