wsx_ws28 For starters, your Apex progress and data is stored on the EA Account that's connected to your Switch Account, (which sadly cannot be transferred over to another EA Account).
What you can do is to contact EA Support and let them know you're having issues signing into the EA Account that's linked to your Switch Account. Afterwards, you'd want to link your PlayStation Account to that same EA Account, (which will work as long as you had never connected another PlayStation Account before, (as linking a platform account creates a lifetime link)).
Another option, (if you're able to sign into your EA Account), would be to sign here: EA Account | Login, and then link your PlayStation Account here: My EA Account | Connected Accounts.
