Trying to play Live Events Co-Op is a nightmare

Been having the exact same issues on pc since release, my connection has no issues nor is the game showing that i had issues on my side. it just disconnects and throws me out.  Sometimes restarting works but never the first game on.

This has been an issue for months, weirdly no comments on it or potential fixes. "deleting tactics" or starting the event through non recommended tab has no effect either.
