I was opening VSCode via WSL, it was loading. I figured out I wouldn't use it, so I closed it, but the terminal closed with it, and I didn't gave it much attention. When I tried opening the terminal again, this is what I saw:
And then, using explorer.exe . I got into the home folder, and my profile 'rodrigo' wasn't there.
I got terrified. I closed the terminal, tried opening up the Ubuntu 20.04 folder from the explorer. It was taking too long, so I stopped it and tried opening again the Ubuntu via Windows terminal and vòilá, it opened. I was relieved.
If it worked, why am I asking about it here? It worked while I was writing this question, so I'll post anyways, as there are only 2 other guys that posted about it, and didn't got a proper response or a solution. In case it happens again, I'm posting this question.
sudo didn't work and neither did apt or any other basic commands.
