Unreal Engine Issues and Bug Tracker (UE-68592)

Description
An ensure is thrown when opening a project if a custom Project Setting has a reference to a Blueprint that constructs an object. The ensure can be found in the Callstack section below.
Regression?: No
This occurs in 4.20 as well
Steps to Reproduce
Download the attached project
Compile the project
Open the project
Check the output log for an ensure (will have to scroll up)
Result: An ensure was thrown while the editor was opening
Expected: There is no ensure in the log
