When this happens, do you get an error message indicating anything?

It sounds like trouble with imap/smtp protocol.

In your mail app go to the Window Menu, check your Activity and Connection doctor, What do those say ?

Knowing nothing more, I would suggest turning off you icloud account , your computer and sign back into your icloud address.

It is a new protocol implemented by gmail from February 2024. It normally is concerning people sending more than 5000 mails a day. It really is up to you, if you want to follow through with the protocols. If you receive no error from your other devices, you at least have a backup plan.
