Dialog error when playing a Mod

Hello everyone.

I hope you can help me with a bug I had while playing a mod (it also happened to me while playing others). This error occurs when starting a dialogue where one of the characters is supposed to speak.
My version of the game is in Spanish but the mod I want to play is originally in English.
Well, that doesn't happen and I get stuck in the dialogue without being able to skip it or go to the menu.
I couldn't find anywhere someone to solve this error. I remember that someone before passed me a kind of “mod” I think, that solved this error.

If someone can help me I would appreciate it.

Thank you!
