How to reproduce:
- Open the attached project “IN-147015”
- Build and run the project
- Observe the crash or freeze
Reproducible with: 6000.5.0a1, 6000.5.4f1, 6000.6.0b3, 6000.7.0a2
Not reproducible with: 6000.0.79f1, 6000.3.19f1, 6000.4.0a3
Reproducible on: macOS 26.5.1 (M4 Max)
Not reproducible on: No other environments tested
Workaround: Selecting a Render Pipeline Asset in Project Settings → Graphics → Default Render Pipeline
Note: Editor freezes on 6000.6 and 6000.7 streams
