Your error results from the mod system restoring the game using the "backup" folder before applying mods. To fix it, you must start with vanilla Strive game folder, add the "Put in Strive Game Files" to the game folder, and delete the "backup" folder if it exists. Then you can run the game and apply the mod.
Edit: As long as you have the "bodiesnaked" and "bodiespregnant" folders, it doesn't matter how you added them. The game may have errors without them, but this error is not that.

Thanks for telling me this, small question. Do i have to delete the backup folder or is it enough to place it in another location? Also, something that should be mentioned, whenever you start the game anew ( not load when already in the game but start the game using the exe file ) a new backup is created. So you will have delete the backup file everytime you use the exe file to start the game.
With high regards,

The game doesn't care about the status of that folder, so either deleting it or moving it is fine (though there isn't much value in keeping just the backup folder).
The problem is not the existence of the backup folder, it is a critical part of the modding process and it may not work without it. When the mod system applies mods, it always restores the backup first to prevent redundant application of mods. However, due to the fact that Aric's mod has users pre-patch the Strive game folder, this requires the deletion of the existing backup to prevent the mod system from erasing the pre-patch. When the game starts without the old backup, it will create a new backup which will include and preserve the pre-patch.
Thus it is not necessary to delete the backup more than the first time, as the backup folder is only used for applying the mod and has no other effect. Though given the complex installation it is likely that the backup folder has no value for that Strive game folder, so deleting it again will do nothing but waste time. The scene files(which are not compatible with vanilla) are changed by the pre-patch and the backup folder only handles script files. The simplest way to properly restore the game to vanilla is to start with a fresh copy.
