Google, Gmail & MacOS Mail & Safari problems

I have looked for answers online and via Apple Support. It seems there is a problem which is not only confined to older Macs (the MacMini is on Monterey 12.7.4) but has also been reported with devices on Sonoma. Apple support failed to provide answers, except to upgrade to 12.7.4, or to seek help from Google – or not very explicit, buy new Mac! Many with the problem report receiving 'Error 400' from Google.
Am writing this from MacBook Air, which thankfully still works. Ideas or comments please. John Elton-Wall
