INFO: I am in the launcher Beta program.
So, I load up Minecraft just as any day, but ooh, an update. But after a minute or two of updating, It gives me an error (I can't show because I am writing after uninstalling the launcher). I uninstall the launcher and reinstall it using my existing MSI, but, what's this? Another error (shown below)? Oh boy! I guess I can't play Minecraft: Java Edition until I get an informative reply on this thread!
