Invisible World Border

THIS BUG WAS FOUND IN 1.20.1

I was experimenting in a minecraft would to get past the world border but when I teleported there, there was no world border, but I couldn't see it and I could not mine or break blocks near it. But items went though.

I have a OneDrive link below and in the link, there is a video.
