Please make sure you've extracted the desired patch's folder to the game's "mods" folder (instead of extracting the loose files from its folder into "mods" directly), so its path should look something like AppData\LocalLow\Glitch Pitch\Idol Manager\Mods\uncensor_ru_x if you were to download and install the Russian Spicy version of the patch, for example.
Have you tried installing any other non-Steam mods to your game, such as my own IM:SOOF pack, or this other mod? Do they work appropriately?
