I recently got crashed in the launcher and unable to get into the Minecraft server  with something about code 0. I mangage to get back in by using task manager to close the launcher when I get into the game, but then what happened was I either turn into Steve with the skin that I made yesterday or most of the people I saw in any server turn into Steve or Alex.

Is there anyway to fix this? My IGN is MoonPie6000
The picture below is showing people in the server had become Steve and Alex. I asked one of my friends to look at my skin and they say my skin is not Steve or Alex but myself and I also see that too.
