Why would a girl block me after over a year of no contact?

Not much to it, I was talking with a girl for a few months back in late 2022 and we had a mutual friend who kinda ruined it for us. We haven’t spoken since December 2022 and just a month or two ago she blocked me on Snapchat. She had blocked my number March 2023 and then blocked me on tiktok in July. Any explanation?
