I am trying to get Righteous achievement but somehow I got Survivor achievement despite getting Esther and Sophie to train successfully. I am asking if you can help me in this game problem?

As the title says I just finished the demo and bought the game, loaded it up and continued my save but no achievements are popping up

In the demo I managed to win it few times. I full version I'm almost at the end of the content that was available in the demo and I think I won only once. No matter if it's hard or easy. Just lost one with +16 and "easy" Either I'm the unluckiest player ever or this game is setting me to fail from the start :(...

How do I get it? I've tried hard, but it's not easy.

I tried verifying the the files through steam. but the game does not allow me to continue from a save. The candle remains lit. I reinstalled the game in the c: folder and it kinda looks like it is working, but now when loading a new part of the map the game looks stuck again and the candle remains lit. This is really weird. I have a 2023 high end MSI computer with a GTX4070. I never had this problem with more demanding games than this one...
