i have the same problem, i used a year to create a world, almost done, and no i cant play. i cant use the orgin app for they have blocked it, and the new ea app launch it wrong, so now i playd for a year for nothing. im so frustraded... and i cant find a way to contact ea from my location eather. hope they fix it for this is not fun.
I am noticing this same issue - CAW (Edit In Game) does not load properly. It worked fine yesterday, but it is broken today. I might have known this new app would be the culprit.
I was forced to update, as exiting out of TS4 prompted an undeletable pop-up on Origin telling me it was time to update.
It would appear that the "new player experience" EA promised us through their new application is a new level of inability to play one of their games.
