Word not saving new document
Strange issue with Word, coming back from holiday: I can't save a new document or save as... an existing one. The new file will appear in the finder, then disappear after 1 second. The name of the file will then be changed to a temporary file name.
The issue happens on my iMac and not on my MBP, which are linked through iCloud.
I have completely reinstalled Office (v. 16.52, but other strange thing, Product ID is 00000-000-000000!) and OS is also latest (11.5.2).
Any idea of what I can do?
Thanks
PS: I thought I was posting this in "windows software" topic, but now is in iCloud. oh well
