Script Editor: Fails to Open

Hello All and @eirannejad

although it is unique to my PC I’m running into this error trying to load ScriptEditor,

Error 12/21/2024 10:14:16 AM [RhinoCode] Error opening code editor | System.MissingMethodException: Method not found: 'System.Threading.Tasks.Task Ed.Eto.Ed.ResetThemeBackgroundColorAsync()'.

Solved by:
1- Uninstalling Rhino 8
2- Strangely the files under "C:\Program Files\Rhino 8" remains by the folder and it is locked by the system. , deleting these files and reinstalling solved the issue.

It seems I was dealing with old dlls from an ancient build of Rhino 8
