    Code (CSharp):
    1. Error building Player: Cannot destroy GameObject that is part of a prefab instance.
    2. UnityEditor.BuildPipeline:BuildAssetBundles(String, BuildAssetBundleOptions, BuildTarget)
    Unity 2018.3b1, occurs when trying to build asset bundles, regardless of build target or settings.

    Working on trying to reproduce this in a smaller project, will file a bug when I have it ready.

    This probably happens because of GameObjects with EditorOnly flag in prefabs.

    There is a fix coming in a future beta.

    Unfortunately I think you have to wait to beta 6 or 7. Even though the issue is fixed getting it through the release pipeline can take a little while.

    Hi @LeonhardP and @SteenLund
    The issue, or one similar still exits, and I can even said appeared in 2021.1.1f1 compared to 2019.3.6f1. I opened an issue, ticket 1363573 in fogbugz. The difference with the OP is that the error appears when exiting playmode.
