Unreal Engine Issues and Bug Tracker (UE-68035)

Description

When using FText::FromStringTable to initialize an FText variable in the constructor of an FStruct that inherits from FTableRowBase, an assert is caused due to recursion. The assert is as follows:

Assertion Failed: RecursionNotAllowed.Increment() == 1

Regression?: No
This occurs in 4.20

Steps to Reproduce

Download the attached project
Launch the project to Windows or any other platform
Result: An assert is thrown, causing the program to close
Expected: The program launches properly
