Project hangs at 73% error in c++ how to fix?

Question

C++ / C#

Please help, am I doing something wrong? but when I run the unreal engine 4 project it crashes, when I run it through visual studio 2017 it shows this error and the project freezes at 73%, after which it also crashes

Run under a debugger and see where you have a null pointer.

Answer 2
