Player built for Windows silently crashes when UI Prefab is instantiated and Render Feature "Render Objects" is active in PC_Renderer Asset

Sep 25, 2025

How to reproduce:
1. Open the attached “IN-114498” project
2. Navigate to File > Build And Run
3. Click “Yes” when prompted
4. Once the build finishes, wait for ~10 - 20 seconds
5. Observe the crash

Reproducible with: 2023.3.0a6, 6000.0.59f1, 6000.2.7f1, 6000.3.0b4, 6000.4.0a1
Could not test with: 2023.3.0a5 (could not solve the “NullReferenceException: Object reference not set to an instance of an object” error when trying to build)

Reproduced on: Windows 11, macOS 15 (M2), macOS 15 (M3) (user reported)
Not reproduced on: No other environment tested

Notes:
- Clicking on the screen can cause the crash to occur in less time
- If "Render Objects" is disabled in the PC_Renderer Asset, the crash does not occur
- Sometimes a “UI Toolkit Crash.exe is not responding“ pop-up will appear, other times, the build will close without warning
- The crash does not occur when building for Mac

I have a similar issue using UI Document in World Space. I add this render pass to exclude post process effects from world UIs.
It crash a few seconds later after rendering the UI.
