To mods and bug fixers

Also dont close this report because of this “We're tracking this issue in REALMS-2146, so this ticket is being resolved and linked as a duplicate.” because this report isnt being updated or worked on.

i put this problem on reddit lots of other people having same issue.

no fixes from reddit or this bug forum

tested fixes (none work)

turning off the realm

editing world files to make them smaller

disabling window virus threat protection and firewall

creating a brand new world and uploading that

restarting computer, minecraft, launcher and logging out of them

Thank you for assistance with this problem 🤓
