it wont load. I even restarted my computer

I don't even know if you are referring to the mod not loading, or the schematics not showing up in the Load Schematics screen? And you said "maps" - did you put schematic files or world downloads in the schematics folder or what exactly?

Also kinda unrelated, but your Litematica mod file name indicates you probably downloaded it from one of the so called "mod repost sites" like 9minecraft. Please don't download anything from those sites, they just re-host mod files without permission, and there is no way to tell if they change the files in some way, or which version of the mod they have. In general you should only download mods from CurseForge, Modrinth or GitHub. There can be some exceptions, for example I have some early development and testing versions on my server. But any such links should then come from a "trusted source", like linked from the official mod page on CurseForge or Modrinth, or from the author's Discord server etc.
