The Editor freezes indefinitely when setting the Parameters list element number to a very large number in the Filter Function Definition

Unity: UI Toolkit Framework

Won't Fix

6.4.X

6.3.X

We won't artificially limit the number of filter functions because of slow Editor updates. That being said, there's a general Editor performance regression under investigation that may help with showing large amount of items for SerializedObjects.

Steps to reproduce:

Create a new Unity project using the Universal 3D template
Create a new Filter Function Definition (Assets > Create > UI Toolkit > Filter Function Definition)
Select the newly created Filter Function Definition
Change the Parameters list element number to "999999" in the Inspector window
Observe the Editor

Actual results: The Editor freezes indefinitely

Expected results: There is a limit or validation to prevent freezes/crashes

Reproducible with versions: 6000.3.0b8, 6000.4.0a4

Can’t test with versions: 6000.0.61f1, 6000.2.10f1 (due to no Filter Function Definition feature)

Tested on (OS): MacOS Silicon Sequoia 15.6.1, Windows 11
