Word crash after 365 update

First thing today, I updated my 365 software since my Word has been freezing/auto-restarting. The updates installed fine. Since then, though, Word has crashed no fewer than seven times--a record for one day. I tried doing a quick repair, with no luck. Now I'm doing a full online repair--inconvenient, since I need to use the software but now can't.

Have others reported similar crashes after updating? How can I repair? I need to be able to use Word/Office, and I expect to resolve fully since I'm a paying customer. Thanks in advance.
