New Word or PPT document cannot be saved in a desktop file

Hi,

Suddently, I can not save a Word or PPT doc on my desktop or into an existing file. Excel works fine.

When I click on "save" or "save as" nothing happens, not even the usual pop up menu.

File is never saved on desk top, cloud or One drive

When I open an existing file it can be saved under the same location and name, but no pup up menu.

Going tru some postings on thid matter, I reinstalled OS Montery 12..0.1 and the whole window suite.

I also shut off and reoppenned the system many times
