We’re tracking this already. It sounds like it’s only happening to offline characters.

We’ve deployed a hotfix to address the catalyst not letting you empower the monolith in offline.

For those who are experiencing this issue in online:
Do the indicators around the catalyst illuminate for the requisite timelines after you’ve defeated the boss of that timeline and received its blessing? The three timelines that must be completed are Spirits of Fire, The Last Ruin, and The Age of Winter.
Are you able to walk up to and click on the catalyst, or is it inaccessible due to the rocks not being formed around it?
If you fully exit the game and then return to the catalyst, does any of this change?
