Mendeley Add On Permission Error on Personal Device

I have the same issue right now.  I have used Mendeley for years on my personal computer as a word plug in an suddenly now I can't in September 2026. I'm on a personal computer but my workplace just upgraded to Microsoft office 365 and I'm trying to update a research paper that is work related.  I've accessed my work email on my personal computer and now it seems my own personal version of word can't accept plug-ins.  

I don't understand how to get all of the office accounts untangled.  I have accounts for my kids school, my work, my school and now it seems each one takes control over my personal version of office. I have signed out of everything I think.

I'm on a tight deadline to reply to the Journal's reviewers and now I can't access and update my references! Please help!!
