Possible problem with FMLInitializationEvent

MCreator Version: 2021.3 | Forge Version: 37.1.1 | Minecraft Java Edition, Version 1.17.1

No matter where I search for a possible solution to this problem. I'm still lost within the forums, webpages, and external links.

An attempt to create a class for IProxy, ClientProxy, or ServerProxy. An error occurs, for the imports from Forge.

Console Output: IProxy.class Test

After following https://mcreator.net/wiki/gradle-setup-errors#wiki-index-1, Errors still persist, with no visible answer.

Others throughout other forums in the Minecraft community have mentioned that they built completely fine in older versions of MCreator and older versions of Minecraft.

I also see the problem within other forum posts on MCreator.net as well from other members.

If there is a possible fix to this persistent problem, any help would be greatly appreciated!

Kind regards, GregoryAM.
