Strange behavior with object references after update to 2019.3

I just updated my project from 2019.2 to 2019.3. All of a sudden I'm having issues with object references getting unassigned (both in scenes and in prefabs). Here is one example, if I click on this prefab asset in my project, in the inspector it shows that the fields are unassigned (first screenshot). Once I open the prefab by double clicking on the asset, the fields are assigned (second screenshot). The fields are also unassigned if I drag the prefab into the scene. Am I insane, or is this a 2019.3 bug or an issue with my project?

I'm getting exceptions from this when I hit play. Basically my entire project is broken now.

 

It seems like this bug. Other people are saying it is not fixed also.

Update: This was resolved by reimporting everything.
