The restoration patch does not add new scenes, it only adds the sexy parts of the scenes already in-game. So if you're trying to apply the current restoration patch to an older version of the game, you're going to run into problems.
You can verify the version of the base game by opening it up and looking at the event log. If the last Chika event is Into the Woods, you have the older base version of the game. If it's The Gap in the Door, you have the current version.
The Restoration Patch is designed for the version of Huggy Boy currently available for free on Patreon, and if you download that and apply the patch, it should work fine for you.
Or just download the uncompressed sexy version.
