Do I figure out a way to Un-invite someone to something or just grin and bear it?

Context. I’ve been on rocky terms with one of my friends recently but we’ve been doing much better so I invited her out to join me and my other friends at an ugly sweater party this weekend. Well lo and behold, yesterday we got into a little spiff but patched it up right after.

However after thinking about it today, I really don’t want her to come on Saturday. I just wanna have a good time without feeling like I’m walking on eggshells around her all night and constantly being hyper aware of everything I’m saying and doing. How do I univite her without being straight up? What are some unconventional ways you can uninvite a person? Or is it too late and I just have to suck it up?
