MCC:
Mission: Long Night of Solace
steam version
I am in the middle of my second playthrough.
I am not able to resume my game.
It crashes back to the main menu when I try to resume the campaign.
This happened to me once too while going through the LASO playlist.
The only thing that worked for me was getting an extra controller so the mission would restart because there were two players. Then I quit out and restarted on solo and it would reset it for me.
Idk if you have a friend that can help you out or if PC has splitscreen to reset the mission that way but I hope this helps
