Unlike a legitimate game that uses a buit-in interface or a language setting within the Steam network, for a cracked game, the language settings are changed within a text file. You would need to go to the installed game's folder and try to find a text file that is called either "steam_api.ini", "steam_emu.ini", "settings.txt", "settings.ini", "language.txt" or any file with a file extension of ".ini" or "txt" (Search in any subfolders, if necessary) and then open it with Notepad. Do a search for "language". If found, set the value to a language that is supported by the game (eg. language = english), save the change and then run the game.
