Export error "This block contains unexpected or invalid content" when after update plugin "ncmaz-core"

Screenshot when have problem

SOLUTION:

Don't worry, after every plugin ncmaz-core is updated, there are always edits (add/edit/delete) in the code of ncmaz-Gutenberg block, so WordPress editor will appear error message like above.

You calm down and just click the "Attempt Block Recovery" button and the Gutenberg block will be restored.

Thanks.
