Dragon Age Origins will not start. Plenty of attempted solutions - none worked.

I am also having this issue. I tried getting help from EA, for them to tell me things I have already tried. I don't know what to do, as the game did work until it didn't. I had this issue with my old pc, and is now doing the same on my new pc. Hopefully, there's a way to fix this, as it's one of my favourite games. All of my other games run fine, it's just Dragon Age: Origins - Ultimate Edition that's having this issue.
