I'm having almost this exact same issue after the most recent update. EA app shows all the games I own, won't launch from either Steam or the app now.
I have an GTX 1070, and deleting the folders in "C:\Program Files\EA Games\Jedi Survivor\Engine\Plugins\Runtime\Nvidia" and then adding -ngxdisable as an Advanced Launch Option for the game in EA Desktop fixed it for me. I used this to get Ground Branch working (Another Unreal Engine game). I'm guessing it's an issue with Unreal and Nvidia Drivers/DLSS...
