Help with mesh/texture or something

I’m making a coin for an animation and I did something that messed everything up. I spent a while trying to fix it and even tried to undo what I did right after I did it but it didn’t let me for some reason. I believe I tried to bevel vertices or make the mouth more circular and then this happened. How do I fix it

Not so clear to see but bevel could be the problem if this is a planar geometry ?

I just restarted lol
