My storage expansion card doesn’t register and I looked inside the groves are messed up for...

You can buy or win extra storage via saddle bags. The merchant inside the putrid grove in novigrad sells +100 storage.

I have 2 external hard drives and the internal storage expansion card, I’ve played the game on internal the expansion card and both of my external hard drives. It has continued to do this on all storage drives and I’ve uninstalled and reinstalled, I’ve completely reset my whole Xbox, I’ve attempted to reset the cache on my Xbox and unplug it and replug it in after a little time. I’ve reset my internet and MAC address, I’ve even attempted to play the game with a different account to see if maybe my account is messed up but none of that has addressed or fixed the issue with the game.

I'm sorry for that. Is the game stored on your Internal Storage or Expansion card? A corrupted expansion card may cause issues as well.

If you're looking for storage for Xbox One or older games, you can use any external hard drive.

If you're looking for Series S/X games, you'd need an expansion card. https://www.xbox.com/en-US/accessories/hard-drives/seagate-expansion-card Western Digital makes one also.

My Xbox has completely restarted. I mean from the very start. I can get back onto my account, but I can’t look at any app, or even access a single game. The games on my storage expansion card aren’t showing up as well. What do I do?

Fixed.
