"failed to load image" is usually related to an image not being in the specified path. maybe you put a relative path, maybe you moved the code files and forgot to move the image, maybe the image name is wrong (you need to include the extension, like "button.jpeg").
you also need to be more descriptive with your problem, since ranting is usually just ignored. your OS, SFML version, VSC version, how did you install SFML, how did you link it in VSC, the exact error mesages, etc...
