Question, the "awc.dll" you downloaded is 912kb big on your hard drive?
There are two possible game related issues here, the corrupt "awc.dll" or a corrupt save game or game profile.
So, don't enable cloud save again. Game Library > right click ME3 > Game Properties > "cloud save" > uncheck cloud save, also check Origin > Application Settings > Installs and Saves >Cloud storage > to be "Off"
Also don't change anything I told you to do before if I don't mention it, running Origin as Administrator for example.
After you disable cloud save again > close Origin > move the entire "Mass Effect 3" folder from your "Documents" folder to your desktop. (The "Save" folder you moved before from the "Documents" folder contains your savegames, right?)
Also move the old DLLs out of the ">drive<:\Program Files (x86)\Origin Games\Mass Effect 3\Binaries\Win32" folder > start Origin > test
