I get error message when I try to intersect/cutout font from image

I have a graphic that I've overlayed front on top of. I select both images>Window>Pathfinder>Minus Front and I get one of two error messages that I screenshot and am including. I've also tried selecting the font > holding down my shift and selecting the graphic behind it > hold down alt > clicking intersect as suggested by someone here on Adobe Support. Both options didn't work. What could be the issue?
