My game won't load in the steam app or EA

As my subject states, my game won't load. I've spent hours searching forums and watching various videos to resolve the issue. I've tried all the suggested solutions, but nothing has worked, and I've invested too much money in the game to consider abandoning it. The initial problem occurred after an update, which caused my custom content to stop functioning. In the process of attempting to fix this, I'm unsure what could have gone wrong. Any assistance would be greatly appreciated. I also included my  DxDaig for reference.
