I'm working on a Minigame on my Realm with some friends, and I wanted to add custom advancements and download a backup in case of any severe unfixable issues due to a miss-typed command, but whenever I attempt to download my world from the Realms menu, it prepares the download and when it starts, instantly goes to "Download Failed" this also happens with any Minigame on Realms that requires a Resource Pack.

I've had numerous issues with my Minecraft, and only mine. My friends don't experience any of my problems, I wonder if my game has some permanent corruption or something.

I've tried to uninstall and reinstall several times but that didn't work.
