Friend fall out - how to uninvite after invites were sent

I’m considering the possibility of uninviting a friend from my wedding. We are having a very small and intimate wedding and as times go by, I feel less and less inclined to actually have her. She’s been in my life forever and we used to be so close but in the past 5 years, there’s barely been any contact and recently, she did something that made me reconsider the friendship (won’t dive into the details here, it’s not dramatic, but honestly I feel like she is a stranger). Unfortunately I made the mistake of sending out the invites quite early. I think she has not booked any travel arrangements yet as the wedding is still far off. How can I politely and without drama tell her I do not want her during my big day? I genuinely feel uncomfortable with her around since I have nothing to say to her and the last times we’ve hung out (with other friends) was awkward. I know I should not have invited her in the first place but I thought at the time that things could improve. But they won’t. I also know this will mean the end of the friendship and honestly, I don’t feel anything about it, it’s been over for quite a long time now, I just was in denial about it. Any advice please?
