End of Line quest soft locked?

I’m in my first play through of the Claptastic Voyage on TPS and during the end of line quest I died as I was chasing after Shadowtrap where claptrap should have opened the exit to the Cortex. But now that I’ve respawned the door isn’t open and I can’t find a way to get the story to progress.

I’ve tried leaving the area, restarting the game, switching missions, nothing seems to fix it.

Anyone found this or how to fix it?

Thanks

I’ve never run into that bug before but I’m looking for someone to help me beat that mission if your available
