Workspace setup failed ( Could not fetch model of type: "EclypseProject" using connection to Grandle distribution: ... )

Hello, recently I downloaded MCreator 2020.5 and added plugin Minecraft Forge 1.12.2 mods generator. When I tried to generate my first workspace, everything looked fine but in the end it crashed and left this error:

After checking common issues, I tried to restart the pc, delete grandle folder, change firewall settings for JDK app and Java, and even tried to turn off firewall completely. Nothing fixed that and my problem continues. Any ideas please?
