Friggin COD BO3 won't start?

I've looked EVERYWHERE haha first, got the message that says "Didn't shut down properly, start in safe mode?" blah blah. Verified game files, ended up just reinstalling, same thing. Then some peopel said it might be antivirus so added that to exclusions, someone else mentioned NZXT CAM and I did have that, uninstalled. Changed/copied/edited config in /players. Everything driver wise is up to date, every other game works. I did end up getting somewhere...now it at least stops after safe mode message. Before it would just run forever without a task actually running. Now it just ends after a few seconds. Driving me ******* nuts, I've tried everything 20 different threads mentioned. Any other ideas? Maybe a launch option?
