"Regenerate code" not working, with no plugins. How do I fix that?

Here is what the console says:

Reinstalling the version does not work.

I know, but how do I fix it? It's deleted after all.

How do I do that  then? Is there a button to do that?

In what file are deleted elements kept?

It still doesn't work. No items reference unexisting ones.

I can't even migrate the mod due to the errors. When I press "ignore error", no mod element is marked
