MS 365 error message

MS Message on MacBook Air MacOIS 12.0.1 Monterey

after recently upgrading my Mab Book air to MacOIS 12.0.1 Monterey I keep receiving the message below every time I open one app of MS Office 365 the same message appears for each and all MS office apps. Word, Excel, PowerPoint, one-note, etc. after sign-in in all okay, but it happens again every time I open each one app.

I recently updated the MS 365 to the last version.

I checked on the MS 365 page and the version is 16.56 for all the apps.

It automatically updated all just today, but the error message keeps coming up after verifications.

I tried signing in with the two different accounts I have and the message keeps coming up

I tried to open MS word and sign in, when the page opens, normally the yellow spot is not there if I do not physically sign in with the authenticator every time.

then with the yellow spot if I open the blank document the message does NOT come up, but it does come up if I do not sign in

but then if I close and/or try to open an old doc for editing the message comes up again ..it looks like MS 365 does not remember me sign in.

Much appreciate some comments as the date in the message is approaching

Thanks
