Reproduction steps:
1. Open the attached 'FixedBufferOverrideCrash' project
2. Open the 'TestScene'
3. Select the 'TestPrefab' and observe it in the Inspector
4. Add an element to the FixedSizeBufferCrash array
5. Save the Scene
6. Enter the Play Mode and observe the crash

Reproducible with: 2019.4.34f1, 2020.3.27f1, 2021.2.10f1, 2022.1.0b7, 2022.2.0a2

The application crashes with a message:
'The file 'MemoryStream' is corrupted! Remove it and launch unity again! [Position out of bounds!]
AcceleratorClientConnectionCallback - disconnected - :0
Attribute Qt::AA_EnableHighDpiScaling must be set before QCoreApplication is created.

    This strange bug kept showing up repeatedly, and it used to really frustrate me, but thankfully, it's fixed now. I'm so relieved it got resolved before my thesis submission deadline. Now, with the help of thesis support from Germany, I can work on and submit my thesis without any worries!

    When deserializing an array of a type that includes a nested fixed-size buffer field, the editor can sometimes crash. This issue often arises due to the complexity involved in managing memory for fixed-size buffers. Proper handling and validation of these buffers are crucial to prevent memory alignment problems or corruption during the deserialization process. Ensuring these buffers are correctly managed can help mitigate such crashes and improve stability.

    Now I have uninstalled and re-installed unity hub, unity editor and all the files and folders.
    Now when I installed unity hub and tied to install editor, I got unity new version 2021.3.2f1
    I installed that new version and for now I have not faced an error like this.
    Any ways if fixed this error in this new version, thank you so much!!
