All accounts and versions have resetted

After an unexpected shutdown of my PC, while the game was launching, I turned it back on. After opening the launcher I found myself on the login screen. After logging into my account, all of my "installations" (versions) and accounts that I was logged in into were not there. The launcher seem to reset to its default settings. The skin library was still there though.

On the last screenshot you can see the accounts I was logged in before it crashed.
