Artifact slot locked?

I’m currently level 33 just got the second shard for the second vault key in the story. For some reason my artifact slot is still locked it has a red x on it and I cannot equip any artifacts. I read somewhere that it was supposed to unlock after the first vault boss.

Second one I believe. I got a relic drop I couldn’t use from the second Vault and had to unlock the slot before I could equip it still.

It comes from a much later boss, about 3/4 through the game.
