This was originally reported as related to reflection probes, but it turned out that the root cause was in scene template code. See the discussion on Slack here https://unity.slack.com/archives/CJBAA5MV0/p1759753724575839
Steps to reproduce:
1. Create a new Universal 3D project
2. Go to “File/New Scene”, select any of the “(URP)” templates, and press “Create”
3. Add “Light/Reflection Probe” GameObject to the Hierarchy
4. Under the “Reflection Probe” Component, press the “Bake” Button through the Inspector
5. Select “Save Scene” in the “The untitled scene needs saving” pop-up and save the Scene
6. Observe the crash
Reproducible with versions: 2022.1.0b1, 6000.0.59f1, 6000.2.7f1, 6000.3.0b4, 6000.4.0a1
Reproducible on: macOS 15.6.1 (M1 Max), Windows 10 (user)
Not reproducible on: no other environment tested
Notes:
- Not reproducible when creating the Scene with “Basic (Built-in)” or “Empty” Scene Templates
- HDRP does not let you bake Reflection Probes if the Scene is unsaved
