Reproduction steps:
1. Open the attached “repro_IN-74398“ project
2. Open the “SampleScene.unity”
3. Open the Addressable Groups window (“Window → Asset Management → Addressables → Groups”)
4. Clear the build cache (“Build → Clear Build Cache → All” in the Addressable Groups window)
5. Create a new build (“Build → New Build → Default Build Script“ in the Addressable Groups window)
6. Wait for the build to finish
7. Update a previous build (“Build → Update a Previous Build“ in the Addressable Groups window)
8. Observe the results of both builds in the Addressables Report window

Expected result: Results of both builds are the same
Actual result: Total size of all bundles is different in the updated build

Reproducible with: 1.21.20 (2021.3.37f1, 2022.3.26f1, 2023.2.20f1), 2.1.0 (2023.2.20f1, 6000.0.0b16)
Couldn’t test with: 1.19.19 (2021.3.37f1), 1.20.0 (2023.1.0a1) - doesn’t generate a “buildlayout.json“ file after a build

Reproducible on: Windows 11 (10.0.22631) (user’s), macOS Sonoma 14.4.1
Not reproducible on: No other environments tested
