Infinite loading bar with no sign of ending any time soon

Watch the last 3 minutes of https://youtu.be/XzgqDXBhkds?si=TR_cWLDUfRH-8fb8 and you'll see why I won't play minecraft until you ACTUALLY FIX IT! The loading bar NEVER ENDS! I TRIED! NOTHING WORKED! It's been in multi-player since the Copper Age Game drop. I AM FED UP WITH YOU IGNORING THIS AND I DON'T WANNA RESORT TO DELETING EVERYTHING AND NEVER PLAY IT AGAIN. PLEASE FIX THIS! I'VE BEEN REPORTING THIS SINCE THE COPPER AGE GAME DROP CAME OUT!
