Ok is here

Ok I noticed an error, but I can't read it

P.S. I used a test workspace

This error indicates something is preventing MCreator from accessing the internet too. You will need to make sure MCreator can access files and internet if you want to use it

and how do I do this? Disable the AV?

Can it hit the firewall by accident?

Ok maybe I understand what's going on: in a few words MCreator can't download the files he needs to create the Workspace, but I don't understand why

;-;

Guys it was really so hard to say "try to clear your caches" XD
