Importer fails on a prefab that has missing references after upgrading versions



Steps to reproduce:
# Open the attached project or import the attached .unitypackage (if you choose this then you will have to import all the package dependencies that include Cinemachine, NetCode, URP and Input)
# Inspect the *Assets/ModelPrefabs/Player Prefabs/KartA01.prefab* prefab
# It should show up as a Prefab GameObject with a Renderer and several scripts attached to it, but instead appears as a Default Asset

Expected result: the prefab should be imported correctly after upgrading between versions.

Actual result: the prefab is not imported correctly. It cannot be previewed or loaded as a GameObject via script.


Note: jumping from a18 to a19 will result in the prefab getting broken upon import. However, starting with a11, the prefab can be broken by removing components from it.


Reproducible with: 2023.1.0a11, 2023.1.0a19, 2023.1.0b1

Not reproducible with: 2023.1.0a10
