Account Issue
So a couple of days ago I was logged out of my account when I opened the launcher, which doesn't usually happen but I got out and back in then logged in and everything was fine. But then today I tried to get in but for some reason I'm not logged in as DastardlyToast (which is my username) but as the start of my email. When I was logged in with this one, it said I needed to buy Minecraft instead of letting me play, so I tried logging into the account that said DastardlyToast, and I put in my email and my password but then it put me back into the account with the start of my email. I did this a couple of times but the same thing happened, so I deleted Minecraft and reinstalled it, then tried logging in. Now the account with my actual username doesn't even appear and only the one with the start of my email. I tried resetting my password, using codes that are sent to my email instead of a password but nothing's working.
The image is proof that I've already bought the game.

Hi!
Can you sign in on minecraft.net without issues?
Also uninstall the Launcher, delete .minecraft folder (copy its content elsewhere before deletion) and then reinstall, restart your computer.
