The new respawn menu stops initializing after resuming a mission. Instead of the menu appearing you just respawn at the base.
Or
The map screen will open upon dying (without the re-spawn menu however) and then you need to end-task the game as there's no way out of the map screen at that point.
Try to respawn on any resumed mission
