Can't get into EMail on PC

Hi,

 I am having trouble logging in on my PC. Win 11 to my email. All was working, but now, suddenly, wirth no prior tweaking, I can get thruogh logi to password with the saved passaword entered, but when I click I get nothing, no action at all. All other screens working. I can get email on my phone and Ipad via Outlook as a client. It's been like this a week or more.
