[AsyncLoadInEditor] Crash on SerializedFile::WriteObject() when building the project



Steps to reproduce:
1. Open the attached “IN-45795” project
2. Build the project

Expected result: Build completed with a result of ‘Succeeded' or 'Failed’
Actual result: The Editor crashes

Reproducible with: 2022.1.0a15, 2022.3.5f1, 2023.1.5f1, 2023.2.0a13 (all build targets)
Not reproducible with: 2021.3.28f1, 2022.1.0a14 (no "Load texture data on demand" feature)
Not reproducible with: 2023.2.0a22 (Standalone case), 2022.3.23f1
Fixed in: 2023.2.0a14 (Standalone case)

Reproduced on: macOS Monterey 13.3.1 (Intel), Windows 10 (by user)

- Switching platform to WebGL sometimes crashes with a similar stack trace
- Reproduced with Standalone, Android, and WebGL platforms
- Standalone case is a duplicate of UUM-31364.
- Android case seen in UUM-37798 (closed as duplicate of this case) -> see UUM-37798 for more information.

    The workaround is to disable this option before build. They didn't bother adding it to API but you can automatically edit the config file itself.
