"ValidateMenuItem failed" error is logged when right-clicking and dismissing the Assets folder context menu while the Editor is in Safe Mode

Steps to reproduce:

1. Create a new Unity project
2. In the Project tab, inside the Assets folder, right-click, go to Create → MonoBehaviour Script
3. Open the script and add a compile error (e.g., type random invalid text), then save
4. Close the Unity Editor
5. Re-open the project and click Enter Safe Mode when prompted
6. Right-click anywhere in the Assets folder in the Project window
7. Click anywhere outside the menu to dismiss it

Actual result: The following error is logged: “ValidateMenuItem failed because there is no menu named Assets/Create/Scripting/C# …”
Expected result: No error is logged
