Stuck on "Beyond" mission on Shadowkeep

[mon_artea1]

The first time i played this mission, after defeating the boss "nightmare of Crota" i was not teleported back to the piramid. I left the mission and try to restart it, and now each time y start it i get stuck in the map of "nightmare of the dominus ghaul". Is any way to restart this quest?
I attach video of the problem https://youtu.be/E-fEa4y7DsM

Have you tried to jump off the map or blow yourself with a grenade launcher to restart from checkpoint?

I have just blown myself with the grenade launcher. Problem solved. Thank you very much.
