How to reproduce:
1. Open the attached “IN-94731_SceneBuildTesting“ project
2. Open the Build Profiles window (File > Build Profiles)
3. Switch to the “Subscenes 512x512 x 256“ Profile
4. Build the project

Expected result: The “Subscenes 512x512 x 256“ and “Scenes 512x512 x 256“ Build Profiles take approximately the same amount of time to build
Actual result: Unity crashes or takes a very long time to build (1+ hours)

Reproducible with: 1.3.10 (6000.0.45f1), 1.4.0-pre.2 (6000.0.45f1, 6000.1.0b13, 6000.2.0a8)
Could not test with: 2022.3.60f1 (Errors in the Console)

Reproducible on: macOS 15.3.2 Sequoia (Intel), Windows 11 (by user)
Not reproducible on: No other environment tested
