minecraft update loading error

Hello, I'm a korean user. minecraft launcher was updated recently, so i downloaded it. I'm gonig to play for 2 weeks. Something went wrong in the login process.  After two weeks, I couldn't log in to Microsoft and play Minecraft games. I also searched for the word something wrong with the login process, but I haven't been able to play Minecraft for 3 weeks because it popped up in Korean. Please correct this error.
