ME3 MP "Your connection to the game has been lost" bug (PC)

Long term issue, that I and others have posted on previously.  But thought I'd take one last crack at it ...

Whenever the host drops (from either in-match or in-lobby), my player is dropped from the match/lobby with the message "your connection to the game has been lost".  See attached pic.  Every time (AFAIK).  Very frustrating, especially when wave 10 or 11.  As opposed to having a chance to wait for a  new host to be assigned, I'm dropped.  Is there any known solution for this?

More relevant detail:

I have multiple PC accounts.  My main (this profile) is old (pre-2018).  This older account works fine (no drops).

All the rest are post-2018 created.     ALL these newer accounts suffer from the drop bug.  I've tried on my desktop and laptop PC's.  No difference in behavior.  The old account works on all of them. To me, this says it is not a PC issue.  It is a newer account issue.

All bought through Origin/EA, none are Steam.

I will note that some friends bought the game recently (same time as some of my newer accounts) and some have the problem, some don't.

Any help from our resident guru or CM very much appreciated, thanks!
