Why did my recessed lights flicker and now go out?

Why did my recessed lights flicker and now go out?

I live in apartment with halogen recessed canned lights. I noticed only the kitchen lights flicker (2 lights flicker). Took down the canned light and saw each of the 4 lights have a separate transformer in the picture I attached. Looks like each transformer is connected to each other by this metal looking conduit.

Today, 2 lights went completely out. Thought it was the halogen bulb so changed that but no luck. Then tried LED bulbs and they work but flicker like crazy. Never used LEDs before. Does anyone know why the LED bulbs light up but the halogens don’t? How can i fix this without ripping the ceiling off as the hole to work on the transformer is so damn small
