Did you install any mods?

Is your mod folder called "mods" or "Mods"? Try naming it to "Mods" if it isn't, I don't know if it makes a difference but the problem seems to stem from the game thinking there's no mods in the "Mods" folder.

What mods did you download? Go into your Witcher 3 directory and find the mods folder--are they in there? Is your game updated?

Assuming you want to access the game's texture files, you need to instead unpack the bundle files inside or within the "content" folders. I don't really know what those other files are but I don't think they're important. Here's a tutorial on how to unpack .bundle files https://www.youtube.com/watch?v=7niPpbpM4HE
