Hi there,
when I try to edit some of my Custom Field Groups, I get an error message: Something went wrong. Please try again!
Console says: [Error] SyntaxError: '#603554e9c31e3' is not a valid selector.

Perplexity suggests this:
We can reproduce a builder crash when editing multiple custom field groups in Meta Box AIO.
Our field-group JSON uses valid IDs only, for example nd-gallery-news-field-group and field IDs like nd-gallery-news-content.
However, the builder throws SyntaxError: '#603554e9c31e3' is not a valid selector, which suggests Meta Box generates an internal element ID starting with a digit and then passes it unescaped into document.querySelector().
After that, a secondary error appears: TypeError: null is not an object (evaluating 'document.querySelector("#post_title").removeEventListener').
This looks like a Builder/React frontend bug rather than a field schema issue. Please check whether internal IDs should be escaped with CSS.escape() or accessed via getElementById() instead.
