Thank you very much!!
I've ran it on debug, didn't seem to work, so I restated everything and finally I got my sfml window. I don't know what was the problem but thank you for helping!!!
Can't seem to change the title to [solved]
Edit:
I think the issue was that the SFML file was in my documents file when my program was in my USB so that it couldn't find it. I changed it so that the SFML file is now inside my USB as well
