Apex Legends won’t start on the Nintendo Switch
This happened to me AFTER I changed my password. Someone else in an unofficial discord server had this EXCAT same issue.
Are you able to again try to reset the password on the related EA account?
To do so, go to help.ea.com, then log out, and then log in using the relevant system portal (PS/Xbox/Switch/PC), then try a password reset. This may help to get this sorted without having to contact EA help.
This may not work, at which point you can contact EA help by:
