I’m getting the error ‘unable to update Native Launcher.’
First, try uninstalling your Launcher and then reinstalling directly from the Microsoft Store at https://aka.ms/NewMCLauncher.  

If you’re still hitting this error, try repairing the Launcher using the following steps:

1.Go to the Start Menu
2.Right click on the Minecraft Launcher
3.Select ‘More’
4.Open ‘App Settings’
5.Within these settings, click on ‘Repair’ and ‘Reset.’
If those steps don’t work, try running the Minecraft Launcher in administrator mode, by typing 'Minecraft Launcher' into the Windows search bar, right-clicking the Launcher, and selecting 'Run as Administrator' from the menu. If this doesn't work, try disabling anti-virus software for the Launcher.
