I really haven't done much with the shape other than using a boolean mod and cutting a rounded rectangle out of this larger prism. I wanted to curve everything but to make it look less sharp so I decided on using the bevel modifier. However, when doing so, there are these crazy things that are poking out of the inside of this shape. How do I fix this?

    $\begingroup$ maybe you shouldn't delete your boolean object and provide your blend file so we can see what you did. $\endgroup$

  • $\begingroup$ @Chris How would I provide my blend file? (I've also kept my boolean object, but I've unfortunately already applied the mod) $\endgroup$

The problem is, that your circle object has wrong face orientation. By that everything else does fail.

So select your circle, got to edit mode, press A, mesh -> normals -> recalculate outside and try again.
