Game loads slower in 1.20.80 opposed to the Preview Version

In the 1.21.0.20 preview, game loading and creating/loading up a world was relatively fast. This is not the case in the 1.20.80 release version. The game loads up far slower and worlds take far longer to load/create. This issue has nothing to do with the amount of worlds and other things that are in both versions.
