Why would you mark that as an answer? I very clearly didn't have time to reply and I, the person with the issue, did not say it was the answer to the issue. The reason I didn't say it was the answer was because it was not the answer.
When I try to load either game, either they do nothing, or they flash up the EA launcher as in the screenshot which gives me an error about "background services crashed". I have repaired the games. I have re-downloaded them. I have done every, single, thing I possibly can. I cannot do the things inside the EA App that you described because the EA app will not open for me. I even tried some weird "downgrading" of the EA app which did less than nothing. I have removed EA launcher, I have reinstalled EA launcher, I have repaired EA launcher. I have done literally every single thing that is possible to do. I am a technical architect by trade, I have created some amazing game mods over the years played by millions. I cannot even start either of these games.
I have added both games and the EA app as exceptions in BitDefender but I also totally disabled BitDefender just incase.
The EC app error code, when it does run, is EC:104.
I have run Windows FSC. I have re-installed the entire VC++ SDK. Clean boot mode does nothing. My GPU is fine, it's an RTX 3080. It is not overheating, it is not overclocked.
Here is a video and some screenshots of the entire process.
I eagerly await a real answer.
