Need help through a glitch

I am currently stuck in a glitch on the wildlife exploitation reserve where I cannot get back to bloodwing. She glitched herself out of the arena and when I restarted it put me all the way at the beginning and now I cannot get the doors to trigger open. This is an initial playthrough as well. If anybody is on that mission I would love to join just so I can get past it. I am currently at work but will be home in a few hours

Which doors? You should be able to access the area to fight her .
