Icon field not loading icons in post edit page

Hello,

The issue has been fixed in this commit https://github.com/wpmetabox/meta-box/pull/1553/commits/f43126dd7082e0f201ba54b75726a5ca227135fa
It will be included in the next update of Meta Box.

Update to my last small rant... I did not get to scroll to page two of comments with the provided solution.

After giving it a try on 5.9.1 (manually adding the GIT change) I confirm that FA Free fonts are displayed BUT only after removing and re-adding Icon type field.

when opening up selectbox it seems like ajax could be the failure, it retrieves an html instead of the (i guess) expected json: Uncaught SyntaxError: expected expression, got '<' from ̀term.php - so it looks like a bug, doesnt it?
