Are you sure you fixed ALL errors in ALL scripts? Nothing shows until you do.
Also, generally speaking, here’s some notes on field initializers versus using Reset() function and Unity serialization:
Serialized properties in Unity are initialized as a cascade of possible values:
what the class constructor makes (either default(T) or else field initializers)
what is saved with the prefab
what is saved with the prefab override(s)/variant(s)
what is saved in the scene and not applied to the prefab
what is changed in Awake(), Start(), or even later etc.
So you want to make sure you only initialize things at ONE of the above levels, or if necessary, at levels that you specifically understand in your use case. Otherwise errors will seem very mysterious.
