Addressables build fails if ModIOBrowser from Assets/Plugins/mod.io/UI/Examples/ModIOBrowser.prefab is in a Scene because the asset Assets/Plugins/mod.io/UI/Sprites/modio-icon-color.png is marked with HideFlags.DontSave

[Raidenxd2]

Unity version: 2022.3.29f1
Addressables version: 1.21.21
Scriptable Build Pipeline version: 1.21.23
Mod.io version: v2024.3.1p1

Have no if this is a Unity issue or a mod.io issue

Title, the only way to temporary fix this is to restart the Editor.
The reason why I say "temporary" is because when you modify the Scene that contains the ModIoBrowser prefab or clear the build cache, it fails again
Blank Unity project (template '3D (Built-In Render Pipeline').

After restarting the Editor, the build succeeds

I also tried to search through the code for 'HideFlags.DontSave' and 'HideFlags' but couldn't find anything.

(Will make a pull request later)

Found out how to fix it.
The reason this is happening is because scripts are using the same icon that some UI elements are using.

I fixed by duplicating Assets/Plugins/mod.io/UI/Sprites/modio-icon-color.png as modio-icon-color-script.png and changing its texture type to Editor GUI and Legacy GUI

These are the scripts that have this icon (they are all under Assets/Plugins/mod.io/UI)
