Unable to Log Into Xbox Minecraft Launcher – Microsoft Sign-In Issue

I’ve been unable to log into the Minecraft Launcher through my Microsoft account. It keeps saying, "We couldn’t sign you into Xbox Live." Everything was working fine until yesterday, and the only change I made was updating my graphics card drivers today. I’ve tried using the troubleshooter, resetting, and even uninstalling and reinstalling the launcher, but the problem persists.

I’m really frustrated and not sure what to do next. Can someone guide me on how to fix this issue so I can access my account and continue playing? Any help would be appreciated!
