I clicked the "Declare War" button on Tartessos and it crashed my game. The specific screen is the CB selection screen before you actually declare on them.
I was able to view the screen before, but what changed is that I now have the Colonialism CB against them.

I also verified this by checking if I had another Colonialism CB which I did against Tyragetae, who also crashes when I open the Declare War screen.
I am dubious that is would help, but here is a screenshot:
