Hi, I'm trying to execute the program using Qt Creator, and receive this error (Application Output):

09:27:29: Starting /home/leonardo/cemu/build-MarioUnmaker-Desktop_Qt_5_12_1_GCC_64bit-Debug/MarioUnmaker...
09:27:29: The program has unexpectedly finished.
09:27:29: The process was ended forcefully.
09:27:29: /home/leonardo/cemu/build-MarioUnmaker-Desktop_Qt_5_12_1_GCC_64bit-Debug/MarioUnmaker crashed.

In issues, the code only trow warnings:
