SOLVED: HELP! My workspace is broken after update

Hello, I've recently updated my MCreator to version 2021.3 and now a lot of mod elements does not compile properly! What can I do? This is what is shown after every compilation attempt: https://imgur.com/a/Xs1O2I2

Please help. I spent working on this mod over one year.. Something like that never happened

EDIT: I've followed steps from MCreator knowledge base and my problem was fixed.
