Bug With Envoy Part 2

I'm currently at the part where I need to retrieve the key, but I cannot open it because the grandmaster was bugged so I had to go to temple by myself. How do I solve this glitch? This is so annoying..

 

Where exactly are you? Could you enter the temple at all? How far could you get? The first time I did this quest the exact same thing happened with the Grandmaster, but I was able to do it normally...

 

Im in the part where I need to get the key, which is after getting the key. When I try to open the door in the base, it says I can't open because I haven't interacted with the grandmaster

Nvm i was able to break in using the teleport

Just in case if someone is having the same issue, go to the top of the floor, open two fences that are next to the emerald block with buttons on it. that button opens the basement btw
