macros disabled

I was running zotero normally but the last few days a message appears when I open Word

“macros can not be found or have been disabled.”
and the Zotero Tab has disappeared.

I reinstalled Zotero
I checked in Options > Trust Center > Macro Settings and it was enabled
i checked preferences-word processors-cite-reinstall adds on
and finally I checked
Tools-adds on to be enabled.
None worked.
I run Windows 10, Word 2019, Chrome
I will appreciate any help
Thank in advance
Marianna

I will also like to add that I checked the path
C:\Program Files (x86)\Zotero\extensions\zoteroWinWordIntegration@zotero.org\install
and the file
zotero
had no extension.dotm
and even that I tried to download it again, it was always empty
Your answer was:

What's your full Word Startup folder path, and is there a Zotero.dotm file in there? (You can x out your username if you want.)

And I replied
C:\Users\marpa\AppData\Roaming\Microsoft\Word\STARTUP

But the mail never reached you.
Could you please guide me what to do next?
Thanks for your valuable help
