Reproduction steps:
1. Create a new project from the "Get Started With Unity" template (Unity Hub -> New Project -> Learning -> Get Started with Unity)
2. After the project fully loads, close the "Welcome to the Unity Editor!" pop-up window
3. Select any cube in the Scene view
4. Observe the crash

Reproducible with: 6000.0.50f1 (by user), 6000.2.0f1 (517f89d850d1), 6000.2.7f1
Not reproducible with: 6000.0.0b13, 6000.3.0b3
Could not test with: 6000.4.0a1 (Does not support learning templates)

Reproducible on: Windows 10 (22H2) (by user), Windows 11
Not reproducible on: macOS 15.6.1 (M1 Max)

Notes:

• Crash can occur in other project templates, however, it is rare and inconsistent for the reporters
• Reports from 6000.2.0b6 and 6000.3.0b1 have the same stack trace, but the issue does not reproduce in the "Getting Started With Unity" template on this version
• 6000.0 does not support the "Getting Started With Unity" template, and could therefore not be tested. However, users have experienced the crash on these versions
• From current reports, it seems to only happen with URP
• From current reports, it seems to only happen on Windows
