При запуске окно программы открывается на несколько секунд и закрывается, в консоле выдает это:
"D:\Programming Projects\CPP Projects\Minecraft\cmake-build-debug\source\Minecraft.exe"
Opening file: D:/Programming Projects/CPP Projects/Minecraft/resources/textures/test.png
Process finished with exit code -1073741819 (0xC0000005)
По выводам консоль я нашел строку где ломается программа -
png_read_info(png_ptr, info_ptr); в функции загрузки png, но не могу понять как это исправить
