Bodach Mechanic Bug

I am can't complete the Bodach Mechanic. I just take Damage from things I don't see and if I reach the End I just get a Blackscreen and die.
I figured out that in Wyvern Form I take less damage during the walking part of the Mech but I still die at the end.

I also can't see the left half of the Arena during the first Phase of the Fight. I tried changing the graphics settings but that didn't help.

Here is my POV:

Same issue. Anyone find a solution? or a way around it?
