I have the same issue and checked with support and as expected they can not do anything about it. This is definitely an issue on their end. Question is why hasn't it been fixed already since from what i see it has been a known issue for a good couple days now.
Quick update on the issue with MSI Afterburner RTSS, since yesterday's update for EA App, Battlefield 1 can be launched again with MSI Afterburner RTSS running in the background.
Big thank you to DICE and EA for this 👍🤗
So quick update, it worked for one day and stopped working since yesterday.
Current status, if Battlefield 1 is started with MSI Afterburner running, RTSS including, then the game won't start.
