Microsoft Word takes forever to open
Upon starting my Mac, whenever I try to open Microsoft Word (by opening the app directly or opening a Word file from an e-mail or online), it takes about 15/20 minutes before it actually opens. The app doesn't bounce/there is no colour wheel, just nothing happens until about 20 minutes later when loads of the window open at once. Everything else - safari, outlook, zoom etc. all open immediately with no issue.
It's no use when I'm opening my laptop for university and can't get a Word document to open until 20 minutes into the lecture.
Can anyone help?
