Package ifluatex Error

I am new with LaTeX. I was trying to prepare a presentation with beamer package. However, the error that

Package ifluatex Error: Name clash, ifluatex is already defined

appears whenever I try to run. Btw, on my computer at work even though I use the same file, there is no such a problem. I saw that I may need to update the MiKTeX Console both as a user and an admin, which I did. The problem still remains. Also, I realize that under the packages ifluatex does not appear. I figured if I manage to install that package there manually, I may solve the problem. I would be more than glad if you can help me.
