Nick Valentine "stuck"

[0xNeffarion]

Can someone help me?

I started playing Far Harbor with Nick Valentine as companion, all was good until i went to clear an hotel in which Nick got wounded right before i clicked on a button to go down on the elevator. Since i am in survival, the game told me nick was going back to the Nick Valentine agency (in the commonwealth), so i finished what i was doing and went back to the commonwealth to pick him up but when i try to talk to him he says a bunch of repeated sentences like "What is it?" and the dialog doesn't start.

I cant really use him as follower now, he doesnt do anything else

I tried some console commands but nothing worked that i tried. Is there something u guys know to help?

Btw no i have no save before that thing happend
