Freezes and crashes during game session

Summary

Since the new 34.00 Ecosystem Update, all multiplayer sessions for one of my maps seem to be affected by freezes lasting a few seconds, or up to 1 minute 30, leading to a session crash with a return to the lobby and the error message “We hit a roadblock: network connection lost”.

Additional Notes

It seems players started complain before I updated the map with the new season’s items.
I played 5 multiplayer games, and every time the game froze and crashed, all sessions seem to be affected.
