this is my last resort😓

I am battling with this for like 4 hours and nothing works, so I need to know if anyone had the same problem.

I installed Expanded Storytelling by maplebell. I start the game, create a family and when I wanted to set a relationship between my two sims, I occured this problem (sc below). Basically the text doesn't show up, at all.

I tried everything, from seeing if any of my other mods were colliding with this, to even trying to change my game language to English (and failed miserably, I can only change between Czech and Russian for some reason??). I messaged the creator, but it may pass a few days for them to reply, so I want to ask if anyone had the same problem and how to deal with it. My game is in Polish, but I have English mods without translations and they just show up in English. I tried changing the country in the settings to the US and it still didn't work. Even chatgpt gave up on me💔Please help out cause I'm on the edge of losing it
