The file "VL-Gothic-Regular.ttf" should be in the "fonts" folder
It is, there's even a "VL-Gothic-Regular (2).ttf" and a "VL-Gothic-Regular - Copie.ttf"
It's possible that your path (folder / subfolder / subfolder /...) is too long.
Try placing the game in a directory with a shorter path
If it don't solve the problem, you can also try to directly install the font on your computer
