Help with java compile error!

I know this has been asked a million and one times, but I cant seem to find one with the exact answer I need. I've tried reinstalling, I've tried deleting the caches folder like others have suggested, I've tried restarting, and I've tried using a new workspace, but nothing seems to fix the error, and I only got it after updating, and I don't know how to fix it. So if you could please help, that would be greatly appreciated!

Exact error code:

Task :compileJava FAILED
C:\Users\djbun\MCreatorWorkspaces\test\src\main\java\net\mcreator\test\TestMod.java:55: error: package TestModItems does not exist TestModItems.REGISTRY.register(bus);
