Electronic Arts folder will not create/form on external hard drive

@RedactedXOXO  Reinstalling the game won't have any impact on which user folder it's reading.  Instead, please open this location:

C:\Users\your username\Documents\Electronic Arts

and let me know whether there's a Sims 4 folder or a symbolic link.  They look very much the same, but a symlink has a little arrow on it.  If you see a proper folder, then the symlink is gone, and you'll need to recreate it, after renaming or removing this new folder.

If the symlink is present, double-click it and tell me what files you see where you land.  In case it's not clear, when you double-click a symlink, you're not opening it like you open a folder; rather, you're jumping to wherever the symlink points.  You can see where you are in the address bar, above the list of files and folders.
