C++ with wxWidgets under WIndows - Built binary doesn't fully launch, but sometimes it does

I've been building a project in C++ with wxWidgets for a couple months now and suddenly now, even though the binary .exe file builds, when I launch the exe sometimes (most times) it doesn't show the GUI on screen and terminates but I don't know why. Sometimes it DOES launch and the program works fine. I've tried launching the program: from inside a terminal (power shell or cmd) in VS code (this is how i have been checking the program while developing) by double clicking the exe file from inside a cmd window and i get the same sort of reaction no matter where its run from. i altered cmakelists.txt to turn off building a -mwindows so it will show a console window on launch but there's no segfault or crash message/error. I also have a --console argument that pushes program messages out to std::cout and nothing is shown there when it doesn't launch, except the message i wrote to indicate it's running in --console mode. when the program does launch, everything works fine and messages shown in --console mode as expected. how the hell do you diagnose this? Edit: the source code for this project is here: https://github.com/Cabji/flip-gui/commit/8233b9a7b2825423315dd8e32cf22b1ce7922969 that's the commit that has the launching problem. I'm guessing it is something to do with bad memory allocation, but there's no errors output about this so I don't know?

@Sharpneli oh i thought i had a cmakelists.txt available on the github repo. i'll look into that. i think i figured out i was doing a bit of circular inclusion while trying to make a child class chare data from its parent class. and this was making the unstable exe launch. i sort of reverted my code back and adjusted some of it and it seems to have fixed it up and i got the parent member data sharing to the child class now. i never thought you could get a binary that will run sometimes and not other times.

Have you tried building the same application under Linux? The reason why I'm asking this question is that Microsoft wants to limit the use of building C++ desktop applications on Windows. They want you to use C# instead of C++. I'm not saying that's the reason why your application in C++ fails in Windows, because there can be thousand other reasons, but I'm afraid that the future for building C++ desktop applications on Windows doesn't looks good.

I am unable to get the actual commit but is the problem available in main branch so I can look into it. Also there's no cmakelists file to build the program, I use nano with linux so building seperately with bash is a pain
