Mojang Studios Note

Please note - some users may be encountering an error when attempting to sign in to the launcher due to missing required dependencies, such as the Xbox Console Companion app. More information about how to check and resolve this can be found here: Minecraft Launcher Troubleshooting FAQ - Login Issues

Additionally, you can check that you have the latest updates by going to the Microsoft Store home (aka.ms/MSStoreHome), clicking "Library" and "Get Updates" and letting it run. Ensuring all dependencies are installed typically solves this problem.
