Gekolib block doesn't work at all

I updated my mod to 2024.3. I can't open my gekolib block mod element and I can't create new one. When I try to do this, new window opens and after I type something and try to create new element nothing happenes, it just closes. But everything else works properly and animated blocks that were made before are working when I run minecraft. I don't know how to fix this, help please.
