The game loads and is playable as a guest/non signed in or not connected to my Microsoft account. Since it is not online, you do not have access to your cloud realms/items/friends/skins or anything else. The game gets stuck at the "Signing in with your Microsoft Account" phase. Then, it errors out with Cauldron. I also saw a c-0010 also. I have gone through every troubleshooting step except going out to buy a 5G WiFi adapter as some online have recommended. I am using 2.4G WiFi connection and can play other games as well as access my Microsoft account and features without issue besides Minecraft. I re downloaded the game and the launcher to launch the game (so slow, BTW).
