2. In the menu bar, select “Tools/Test Asset Creator”
3. In the opened window, select “Create and Save Asset”
4. In the same window, select “Delete Asset with DestroyImmediate(asset, true)”
5. Observe the Assets folder in the Project window

Actual result: The asset remains in the project
Expected result: The asset is removed from the project

Reproducible with: 2023.1.0a3, 6000.0.68f1, 6000.3.9f1, 6000.4.0b9, 6000.5.0a7

Reproducible on: Windows 11

Notes:
- Attempting to manually delete the asset immediately after reproduction step 4 prevents deletion and gives the following warning: “The operation "SoftDelete" cannot be executed because the selection is a root folder or an immutable asset.”
- After deletion, the asset appears empty in the Inspector
