Score in processing

My update of 69 pages/2.86MB score remains "Score in processing" for days.
Yes, I asked this to musescore.com support chat and they answered repost it here musescore.org forum (or discord or GitHub)...
I'm not sure it's relative or not, that update was just adding title/composer text section (only first page, few words) and footer copyright text (every page, few words too), but the file size increased from 650KB to 2.86MB. Is it natural?

MuseScore Studio version: 4.4.4
