I get several exceptions/errors with Unity 2019.3. Top of callstack is marked fat.

Joining the bandwagon here.
Started on 2019.3.10f or 11f
My 2019.3.9f1 install works fine.

I started having similar exceptions starting with 2019.3.10f as well, and the issue definitely appears to be with the BetterScriptableObject class. When I ran into this issue, it looked like the only class dependent on this in Rucksack was LocalizationDatabase, which appears to use it as its base class for serialization support.

To get myself operational again without digging deep into trying to fix the serialization problems in BetterScriptableObject, I changed LocalizationDatabase to use the serialization provided by Odin Inspector (which is another Devdog/Sirenix product) called SerializedScriptableObject. The logic behind that was because I assume they have similar purpose and implementation since they both implement Unity's ISerializationCallbackReceiver interface, but with the Odin Inspector version being more actively maintained for the latest Unity releases. I could be wrong about my assumptions, but hey it worked for me as a quick fix :)

This requires you to own and install Odin Inspector to your project, which may not be ideal or possible for everyone, but if you do, it could get you going now.

To try this, it's just a simple swap of base classes in LocalizationDatabase.cs. I used the latest release of Odin Inspector (v2.1.12 as of this post).

Also, do this at your own risk and backup your databases if you want to try this because I cannot guarantee it will 100% work for you; however, I did not notice any issues thus far yet on my side with my existing databases, and importantly, I've been able to continue other work.

public class LocalizationDatabase : BetterScriptableObject

New
public class LocalizationDatabase : Sirenix.OdinInspector.SerializedScriptableObject

seems to work with me, tanx :)
