Error code 0064 keeps being prompted

Since the game was released, I have been unable to log in, constantly receiving error code 0064. During this time, I have tried various methods: restarting the computer, restarting the game, reinstalling the system, reinstalling the game, repairing the game, resetting the game, reinstalling all Xbox applications and services (Xbox App, Xbox Game Services, Xbox Game Bar), logging out and back into my Microsoft account, logging out and back into my Xbox account, enabling all Xbox online settings, reinstalling the Minecraft launcher, using accelerators (having tried three different ones), syncing Windows time and time zone, changing Windows region, logging in on another device (successfully logging in to someone else's account), and numerous other approaches.

I pre-ordered this game on the official Minecraft website. I confirmed that my internet connection is fine and that my account has purchased the game. The account used to log in to the game matches the one used to make the purchase. Even logging into another account on my computer allows access to the game, but switching back to my account still prevents entry. My issue can be reproduced 100% consistently, showing error code 0064 from the very beginning to the present.
