Oct 08, 2025

Steps to reproduce:

Open any Project
In a Scene's Hierarchy create a UI Document Game Object
In the Project Browser create a UI Toolkit Panel Settings Asset and assign it to the Game Object in the Hierarchy
Select the UI Toolkit Panel Settings Asset and switch "Render Mode" to "World Space" and observe the Console

Actual results: Error "Assertion failed
UnityEditor.GenericMenu:CatchMenu (object,string[],int)" is logged, seemingly nothing actually breaks

Expected results: No Error is logged

Reproducible with versions: 6000.2.5f1, 6000.2.7f1, 6000.3.0b2, 6000.3.0b5, 6000.4.0a2

Not reproducible with versions: 6000.2.4f1, 6000.3.0b1

Can’t test with versions: 6000.0.60f1, 6000.1.17f1 (No World Space UI Feature)

Tested on (OS): Windows 11
