Since last week, Mac Mail loses all previous e-mails (in inbox and sent) and have to close and reopen app to bring them

Every time I open an e-mail, or refresh to get new ones, all previous e-mails dissapear from list of inbox and sent. But this only happens on my Mac with MacOS Sonoma 14.1.1. On my iPhone and other devices same e-mail accounts appear normal, do not disappear. So perhaps it is a glitch having to do with sonoma latest version, or zoho changing IMAP/server settings. Either way, it is a problem as I have to close and reopen my e-mails app every time in order to be able to re-download them and have access to all my e-mails again. They are all lost except from some very old ones dated back in 2018. Pls advice. thx
