Yesterday, I moved my Minecraft folder from This PC to Pictures. When I woke up I loaded up my launcher and it oddly made me log in so I did. Then I discovered all my versions had been deleted except for 1.13.2. I pressed play and when it loaded I found it had removed all my servers and worlds.

Put your minecraft folder to back where it was before. Invalid.
"It" did not remove your worlds, servers, and authentication details, you did it yourself.
