Downloaded Mcreator a few times to try and fox the problem and tried to restarted the download process deleting the old files after reinstalling each time and I was still getting this error. Here is the Error report I copy and pasted.

Reboot your computer, go to C:\Users\Absol\.mcreator\ and delete gradle folder in it. Then run the setup again.
Make sure that you don't have antivirus that could be messing with MCreator files too.
