[2019] Can't join existing session after latest update.

When I Join an existing game, I'm immediately kicked out of the lobby and back to the map. I tried restarting the, figuring that would help, but the exact same bug still persists, did about 10 different tries with identical results. I was able to do a solo session and storm shield no issue, and was able to play with no issue before the update. Issue started after the servers came back online.
