Explore meridian structure glitch

Having just got the game vanilla I reached tvhm And entered Tyco ribs. When I try to explore he eridian structure, the objective does not complete. The funny thing is I can pass through the breach and get to elseer and the objective doe nit even complete. anybody got a fix?

Does anyone know a way maybe to reset mission process because I’ve been trying endlessly to get through this glitch and it still does not work.
