Without a more detailed description of the error, there's not much I can do. I can assume it's a gallery bug because, before the second night, you are released into the open world, where the locked secret cards from the gallery should appear. To fix this error, simply create a save and load on it. Or delete the "persistent" file from your saves folder. If this is not the problem, please send it to the Discord channel in the bug thread, and I'll look into it.
