Mission bug. Only petroglyph mission displayed (Destiny 2)

I bought the shadowkeep add-on, went to the mission with the petroglyph, went through it 10 times, I have all the necessary armor, the first time everything worked and I went to the pyramid and got into it, and then something happened and I only see the mission with the petroglyph, which is I would not do.
I will be oooh oooh very grateful
