I actually tried to delete all the files related to the game (Like the .rar files and the game files) and nothing changed.
I lost every hope.

Noooooo I'm talking about the files at C:\Users\PUTYOURNAMEINHERE\AppData. I forgot whether Local, LocalLow or Roaming has it but there should be a folder called "STROBOVSKY" in there. I meant try the save data, not exactly the game data.
Look, I got my achievements corrupted and they were all big red Windows error signs. Maybe your save files are corrupted as well.
