esim not working after iOS 16 beta

After I had updated to iOS 16 beta to test it out, I had noticed that my esim had completely stopped working. I have now downgraded down to 15.5 to see if that fixes the issue. But I still have no esim and no way to connect to my carrier. I had tried to request a new esim off of my carrier’s website, but I didn’t work. I was wondering what to do to fix this issue.
