Welcome to Microsoft Community.

There are many reasons why you can't log in to Minecraft Launcher, but all of them are due to Microsoft Store and related services. I will provide several methods to try to solve this problem, please refer to the following steps for operation:

• Clear the cache on Microsoft Store.
  

1. Press the Windows logo key + R, type wsreset.exe, and select OK.
   
2. After a few seconds a blank command prompt window will appear, which will disappear after about ten seconds and the Microsoft Store will open automatically.This means the cache was cleared successfully.
   

• Make sure you're using the Microsoft Store Install Service.
  

1. Services.msc can be found by pressing Windows Key + S and typing services.msc.
   
2. Locate and double-click the Microsoft Store Install Service; if the status is Running, right-click it and select Restart.
   
3. Change it to Automatic if it's disabled, then click Start and OK.
