Based on experiences so far, I suspect any Microsoft Office app that is out of date or has permissions problems could be the culprit.
While this may not be the total list, a search gives this:
The suite currently includes a word processor (Word), a spreadsheet program (Excel), a presentation program (PowerPoint), a notetaking program (OneNote), an email client (Outlook) and a file-hosting service client (OneDrive).
Different search results indicate may need to add/check M365 Copilot, Microsoft Office Mobile (old and the culprit for some), Publisher, Access, Skype, InfoPath, and Power Platform.
