Since 1.18.2, the client only quits the world loading screen once the chunk it is in has been received. This mod force closes that screen. If you want to fully kill the screen, you can toggle a config option (you need modmenu and Cloth Config API for that).
Credits to the well thought out name go to mdcfe.
You can download the mod from the GH downloads page, CurseForge, or Modrinth
