All my saved emails have disappeared

I have lost all my saved emails dating back to 2021.  No way to recover them seems to be possible.  I have had the same Comcast email for as long as I can remember, but when I go on the website, everything is just gone.  I am still getting emails at the same email address, but cannot find anything saved.  It seems like this has happened to other users and many report they are just gone forever???
