Problems at last boss of Interlude

I cannot progress any further as resets, going to a new area, respawning at check point, etc., have not worked at all. I need a fix please. As I cannot play any further without progressing past this point.

Can you be more specific on which boss you're stuck on?
Also, are you playing as a druid?

Try creating a new instance of the boss area if you can by pressing Ctrl+Click on waypoint there. Also if you're a druid when going to boss area, enter as human form to engage boss - not sure if GGG fixed that druid bug yet.

My fault, I am at Zelina and Zolin (the last boss fight for the interlude). Im playing a huntress and I did try creating a new instance but they are just frozen on the pedestal still.
