problem with .eps files in Illustrator

Hello,
Since I have Illustrator on my Ipad pro, I can't use some .eps files that I use from my Freepik account. Some of them can be used, others not. It's random and it's really frustrating.

Also, I have a lot of trouble working with some heavy .eps files. It lags a lot. I often have to close Illustrator because it crashes because of these files.

Would you have a solution?
Thank you.
