MCreator 2021.2 Java Model Issue (Cannot find symbol)

I get this error over and over again, I am sick of it, and I even searched through the forum, but no helping solution.

There's the console log.

Would be very grateful if I received help.

If this is a duplicate, I am sorry, but since I have searched through the forum so much and couldn't find something fitting, I am creating this now.
