Expected result: UnityEngine.XR.MagicLeap.MagicLeapSettings different serialization layout error is not thrown
Actual result: UnityEngine.XR.MagicLeap.MagicLeapSettings different serialization layout error is thrown

Reproducible with: 2021.2.0b7, 2021.2.0b9, 2022.1.0a1
Not reproducible with: 2019.4.29f1, 2020.3.17f1, 2021.1.18f1, 2021.2.0b6, 2022.1.0a2, 2022.1.0a6

VLNQA00022, Xiaomi Redmi Note 3 (Redmi Note 3), Android 6.0.1, CPU: Snapdragon 617 MSM8952, GPU: Adreno (TM) 510

VLNQA00316, Samsung Galaxy Note10 (SM-N970F), Android 9, CPU: Exynos 9 Series 9825, GPU: Mali-G76

Note:
- On Android, reproducible with IL2CPP Scripting Backend
- On a macOS build, reproducible both with Mono and IL2CPP Scripting Backends

Errors:
The referenced script on this Behaviour (Game Object '<null>') is missing!
A scripted object (probably UnityEngine.XR.MagicLeap.MagicLeapSettings?) has a different serialization layout when loading. (Read 52 bytes but expected 76 bytes)
Did you #ifdef UNITY_EDITOR a section of your serialized properties in any of your scripts?

    Encountering this issue in 2022.1.19f1 as well as 2021.3.9f1.
    Resolution note saying fixed in 2022.1.0a2 seems odd.
