Print format builder not work today

Hi all,
this morning the print format builder not work correct.
Not possible add new section and the html custom editor is completely unusable.
Testing with chrome and edge.


As per the current design, the Custom HTML editor would work when dragged to the particular section of the print format.

The click on the edit header does not work.
Custom HTML fields are opened incorrectly and do not show the formatting buttons so you can not edit HTML code.
The content of the HTML custom fields is duplicated.
I attach some screenshots.
I urgent need to resolve this issue.

The problem has not been resolved and it is very urgent.
I also created a new format but I have the same problems listed in the previous post
