ive been trying to figure this out for months now, I read the same topics but i must not be able to understand it. (although i understand it more than struggling with unity and its crazy bad component system)
im by no means the most competent C++ programmer, pretty sure im barely considered a beginner. but I try to understand concepts such as running my mainloop logic outside of main (as in, declared headers) not sure thats even a good practice but I've seen other games source code do stuff similar. Anyway sorry about the introduction basically I wanted to make it known that I have a bit of experience getting things to work and this does not.

pardon my code it is a mess, but ive been on this same problem for months now, and its been a headache, so its be rewritten hastily quite a few times.
i have other code which loads images just fine, so im not even sure what the problem is at all. 
basically the code will either locate the font and then crash with an exit error of:
-1073741819, googling it found nothing. I cant figure this out to be honest, if someone could point me in the rigth way or some books to look at. Ive never encountered an issue I couldnt figure out like this in c++, im sure im doing something dumb and missing it.
