Workspace Setup Fail 2021.2

I ended up finding a solution to this problem. For those who are having this problem go into your personal folder, there you will find a folder named .mcreator, open this folder and find a folder inside named gradle and then open the file names caches. Delete this folder, if you get a pop-up saying that the file is being used by another program make sure Mcreator is closed, also use task manager to close all programs and processes called OpenJDK Platform binary. Once you do that reopen Mcreator and load your project. It will take a while to load, for me it took about 5 minutes. After this though, you should be able to use Mcreator without this message coming up. If this does not work delete the entire gradle folder and do the same steps, I hope this helps.
