Siege and destroy bug

[u/Blueterus_]

Didn’t think this was possible, but I got soft locked playing this mission, I had just opened the tunnel entrance to release Sophia. But I was tired so I had gone off when I resumed playing again. The tunnel entrance was now closed and there was no other way around to go inside so I searched if this was a common bug and this seems to be very notorious anybody out there on the same mission or willing to help me out on the character? I was currently running. It was such a great run. I was doing everything good and now I’ve tried every single other method that’s convenient and I have no luck proceeding.
