The Engine crash when loading project

Hello,

I have tried to show the mouse cursor when the game is simulated and UE4 have crashed. Since I can’t reload my project because the Engine crash on loading.
I have suppressed the lines that I have added just before the crash in the .cpp and in the .h file, but I have the same issue.

The logs of the Crash :

The crash window :

Have you any Idea of what I must do for the project to be loaded again ?
Thx

It seems that it is the line in the .cpp file which crash the Engine.
Is there another solution to show the mouse cursor in the simulation ?

.h file:

APlayerController* MyController;

.cpp file

MyController = GetWorld()->GetFirstPlayerController();

Im having the same problem and can’t seem to find an answer
