Meet meatslab progression bug

I have just had to reset my playthrough after reaching the meet meatslab mission and went to the anvil before Wainwright stopped talking now to objective marker doesnt update after the transition between floodmore and the anvil so the gate stays locked and I cant meat brick. Not really happy as all my progress is now lost.

Is the opening switch active or not?

No it stays red coloured and I cant interact with it so I cant open it up and the objective marker stays at the transition between the two areas.

Did you used only Fast Travel when it happened or exit/entrance to the area?

I went to the transition gate that says anvil in floodmore I didnt use the fast travel at first.
