Re: Sims 4 not working at start up, due to mods or something else.....
Hi! Sorry to hear you are having an issue with some custom content. I would suggest that you delete those particular files, then go back to where you originally downloaded them, and download them again. Since the files you listed appear to be recolors, make sure you have the original mesh. Recolors won't work without the original.
To test, just now I installed the Pilar_Nature CD Recolour.package, along with the rest of the Nature set, and everything showed up properly, as shown here - https://pbs.twimg.com/media/CHPd7W3W4AAYJ_s.jpg
Also, make sure your scripted MODs have been updated. They often don't work after a new patch and cause most of the game errors, such as the game not starting. If you have any script MODs installed, such as the No Censor Blur or the Go To School mod, you'll need to update them, or remove them until the creator updates them.
(CC and Mods are not the same thing and don't perform the same function in game, even though you put them into the same folder. For example, CC might make your couch look pretty, but a Mod will make it so you can sit sideways on the couch. As this affects gameplay, it is the most likely reason for a game to stop working after a patch.)
