Steps to reproduce:
# Create a 3D project
# Add any 3D game object for example "Cube"
# Go to the "Window" menu and select "Search" ->"New Window"
# In the "Search" window click the "Inspector" button and verify that the "Inspector" section becomes visible
# Type "Cube" into the search input section and click "Enter"
# Verify, that the results list for the "Cube" is displayed
# Clean the "Cube" search criteria and enter AAA and click "Enter
# Verify, that you get "No results found for AAA"
# Still, click "Discette" next to the search input field
# Select the "Save Project" option
# Leave the proposed default name and click "Save"
# Verify, that the saved query becomes displayed in the "Project" section
# Verify, that AAA.asset is displayed in the "All" tab
# Close the Search window and open it again
# Select AAA.asset in All section
# Verify, that the "Inspector" tab displays its data
# Click the kebab button next to the "Open" button in the "Inspector" tab
# Select "Delete"
# Confirm the action in the Delete popup
# Observe how data changes in the "Search" window: in the projects queries list, main results window, and in the "Inspector" tab.

Expected result: AAA query and AAA.asset and all its data with the access buttons should be removed, because it is deleted. Added video and screenshot in the "Attachments" section.

Actual result:  Inspector tab still displays some data and buttons to access it. But when you click them, nothing happens.
