now I create new AssetBundle and try to build it but I give error message:

Cannot mark assets and scenes in one AssetBundle. AssetBundle name is “angie_character”.

UnityEditor.BuildPipeline:BuildAssetBundles(String)
CreateAssetBundles:BuildAllAssetBundles() (at Assets/Editor/ExportAssetBundles.cs:8)

how to remove this AssetBundle?

you must be mark Assets folder as “angie_character”.
Do the following steps to fix it:
1、select Assets folder in project view.
2、right click in blank space in Assets folder
3、you will see Assets folder in Inspector view.
4、Set AssetBundle label to “none”.
