Invalid Game License

I have owned the game The Sims 4 for nearly 8 years now, I have over 8,000 hours played, but suddenly The EA App is giving me the pop up Invalid Game License. I have tried troubleshooting, I have uninstalled and reinstalled, I've tried clearing the cache, I've removed all my mods, and despite all this effort it continues to pop up. I have no problems loading into my other games, it's just The Sims 4 that is giving me this problem.
