Stuck in an email verification loop

Hi all, this is the first issue I’ve ever had with my wordpress site but extremely frustrating.

I logged into my wordpress site and updated plugin’s, theme and latest security patch for wordpress. All worked fine.

The following day I tried to login and got the prompt to verify my email address. Email arrived in my inbox and clicked on verify. Login page confirmed successful verification and continue to login. Entered same details and get the verify email prompt again. And so the loop continues.

Any ideas how to fix this?
