Need help with error code 0x80070570

So for the past 4 or 5 days, I've had trouble installing Fortnite. One morning, I woke up to play and I wasn't able to. I was given an error message that said the game was corrupted (error code 0x80070570), and I was prompted to uninstall and reinstall the game, and that is what I attempted to do. When I tried reinstalling it, the installation immediately stopped and I haven't been able to do anything about it. I have tried restarting my Xbox One S console, performing a factory reset, clearing my local saved games (for some reason, I didn't have any save data for Fortnite when I attempted this the first time), I have contacted Microsoft directly, I've power cycled my console, I've removed and re-added my profile, I've tried installing the game with a different profile, I've checked for console updates, I've cleared my alternate MAC address, and I've tried downloading it offline. I did all of this to no avail. And if you were wondering, no, I do not have an external storage device. If anyone can offer me some actual help, that'd be much appreciated.
