I had to upgrade my project from 2018.2.18 to 2018.3.2 because a feature I needed. After this all seemed normal, but when I modify a script with FMOD references, the inspector starts to show command errors. I was told that could be because the FMOD manifest is refering to the old Unity version. How could I change it? I tried as well to change FMOD version, to repair/Regenerate FMOD files so the manifest update, but I get an error as well. The errors on Unity Editor are: -GUI Error: You are pushing more GUIClips than you are popping. Make sure they are balanced. -NullReferenceException: Object reference not set to an instance of an object UnityEditor.InspectorWindow.DisplayRemovedComponent (UnityEngine.GameObject go, UnityEngine.Component comp) (at C:/buildslave/unity/build/Editor/Mono/Inspector/InspectorWindow.cs:1353) -NullReferenceException: Object reference not set to an instance of an object UnityEditor.InspectorWindow.DisplayRemovedComponent (UnityEngine.GameObject go, UnityEngine.Component comp) (at C:/buildslave/unity/build/Editor/Mono/Inspector/InspectorWindow.cs:1353) The error while upgrading FMOD is: Copying Temp/Export Package/[…]/asset to Assets/Plugins/x86\_64/fmodstudiol.dll: Access Denied ---

The integration should not be causing any issues like that, I would try closing Unity and deleting the Library folder (Unity will rebuild then when you open the Editor next). ---

Exactly what happened! Thanks! Seems like temporal files were messing with my project.
