Cannot load Microsoft Realms on PC, Tablet, or Xbox One

Hello, I cannot access my Realms subscription saved world on any device I own, including the following:

• Microsoft Windows 10 PC
• Microsoft Xbox One
• Samsung Galaxy Tab S6

. The game does one or more of the following:

• Instantly crashes upon opening, gives error
• Instantly crashes upon opening, does not give error
• Does not allow for the world to be downloaded, fails/crashes
• Allows for world to be downloaded, fails to open
• Opens world, does not load more than 500 blocks surrounding
  • Does not save the game
  • Crashes if you get too close to the edge of the limit of what has loaded
  • Does not allow inventory to be opened
  • Does not allow chests or minecarts to be used
  • Consistent lag
• Opens world and allows the game to load beyond 500 blocks
  • Does not save the game

I have done one or more of the following to resolve the issue on my own:

• Restarted my modem and router
• Restarted my Microsoft Windows 10 PC, restarted Minecraft
• Restarted Xbox One, closed/restarted Minecraft
• Restarted Samsung Galaxy Tab S6, closed/restarted/uninstalled Minecraft

I have been unable to access or use this game for the majority of day today 10/10/2021. This is using the $7.99/month subscription for Realms Plus in the "DNU" realm. The world is called Pompeii, which I find very ironic given this situation.

Please let me know what I can do to resolve this issue.
