The usual view when entering the room

The enemy hiding on the left side of the doorway
5. Teleport to the Courtyard (First Floor) or alternatively the Cavern of Corrosion: Path of Gelid Wind as it is closer to the quest marker. BE CAREFUL WHEN ENTERING THE ROOM, as there will be enemies waiting to ambush you on the left side (refer to the image above). You will want to sprint past the door or use an attack that goes through walls.

6. After the battle, speak to Lamina then teleport to Special Purpose Lab, you have to fight an Ice Out of Space so be sure to bring either a Fire/Wind/Quantum dps or a strong shield breaker such as Asta.
7. Speak to Lamina after defeating the Ice Out of Space, then return to Master Control Zone to speak to Asta and Capote to complete the quest.
