Hi Holger,
Thanks so much for being an angel for helping out in your own time with this. Much appreciated! EA should hire you! After trying everything, I found my solution and would like to share with you and others who have this issue.
Just a heads up, for those running Sophos Home Premium like I am, I'm just going to provide a link:
https://support.home.sophos.com/hc/en-us/articles/360000501206-Exploit-exclusions-Windows-Local-exclusions-
This page basically details how - through your local Sophos widget - to set a 'Local Exclusion' for MassEffectLauncher.exe.
Hopefully this helps someone else and spares them a headache!
