DisplayName field missing from registry - pop up

Whenever I try to run the Sims from the EA app, it brings me this pop up that says the DisplayName field is missing from registry. I sign in with my correct ID and password and it takes me to the EA app, but then when I try to load the Sims 4, the pop up appears. How do I fix this issue? I haven't had any problems with the Sims 4 until now, I don't play with mods, any my drivers are updated. Help please
