ME3 Legendary Crashing On Launch

How did you turned of cloud sync?
Was it still tuned of as you moved the save files? 

I turned off cloud sync on steam and went offline on the EA APP; both were turned off when I moved the save files.

Ok, try it this way:

1. Make sure Steam and EA app are closed.
2. Disable the internet connection of your PC.
3. Go to your "Documents\Bioware\Mass Effect Legendary Edition\” folder.
4. Move the "Save" folder and the “LauncherConfig.cfg”, “TrilogyGamerProfile” and the “TrilogyGamerProfile-XXXX” file to your Desktop. (The folder and files must be gone from the original path!)
   Do not restore the internet connection until you tested the game!
5. Test the game.
   
   If the game still don't works:
   
   1. Press Windows key + R to open the Run dialog box.
   2. In the new Window, type or copy and paste "%LOCALAPPDATA%\CrashDumps" (Without the quotation marks) > Press ENTER
   3. Check to see if there are any "*.dmp" files named after the game exe in the ".Local\CrashDumps" folder.
   4. Zip 2 - 3 ">Game.exe<.dmp" files together and upload them at a free file hosting service like Dropbox, or you can use your OneDrive "public" folder
   5. Post the link here.
      
      

    If there aren't any dump files of the game:

   1. Press the Windows key > Write: Command Prompt > Right click on "Command Prompt" in the search results > Run as administrator.
   2. Copy and paste:
      reg add "HKLM\Software\Microsoft\Windows\Windows Error Reporting\LocalDumps\devenv.exe" /v DumpType /d 2 /t REG_DWORD
      into the prompt Window > Press ENTER.
   3. Play the game until it crashes.
   4. After the game crashes, let all Windows crash dialogues finish.
   5. Press the Windows key and "R" at the same time.> Type "%LOCALAPPDATA%\CrashDumps" (Without the quotation marks) into the new window > Press ENTER.
   6. Zip 2 - 3 "*.dmp" files named after the game exe together and upload them at a file hosting service like Dropbox or you can use the OneDrive "public" folder.

Tried it the way you suggested, still no luck for me.

There were, however, a bunch of crash dump files:

Sorry for the late answer, live interfered yesterday. 

All your DUMP files show INVALID_POINTER_READ accesses violations. 
This means that "MassEffect3.exe" or a function that it called used a pointer that was invalid, either because it pointed to zero, because the memory it pointed to had already been freed or the memory address was invalid. 

All that equals a accesses violations and the program is terminated.  

The problem is that this can have many reasons:

1. Hit Windows key and X.
2. Choose either “PowerShell (Administrator)” or “Command prompt (Administrator),” or "Windows Terminal (Administrator)", whichever option is offered.
3. Inside PowerShell, CMD or Terminal enter: (You can copy and paste the following cursive text.) DISM.exe /Online /Cleanup-image /Checkhealth
4. Press ENTER.
5. If errors are found, notify us. If no errors were found repeat steps 1 & 2.
6. Inside PowerShell, CMD or Terminal enter: DISM.exe /Online /Cleanup-image /Restorehealth
7. Press ENTER.
8. The system will start validating soon. If it throws an error, please list it here.
9. After it reaches 100% repeat steps 1 & 2.
10. Inside PowerShell, CMD or Terminal enter: sfc /scannow
11. Press ENTER.
12. Post the message you receive at the end of the processes here.
    
    Then:
    
    

Please preform a Clean Boot:
