I promise I already searched for this!
The problem I am facing is that I deleted all of my directories, or at least all of the ones that showed up in Jupyter Notebook. Why, you ask? Because I am a fool.
TL;DR:
I think the crux of the matter is that /Desktop is not a recognized directory anymore. However, I also cannot create this directory. It is stuck in limbo.
Here is some code from terminal:
paul@Paul:~$ cd Desktop
bash: cd: Desktop: Not a directory
paul@Paul:~$ mkdir Desktop
mkdir: cannot create directory ‘Desktop’: File exists
MORE INFO:
As mentioned, I deleted everything that was showing up in my Notebook. My desktop is now devoid of all files, which have been relocated to Trash. However, when I try to recover them, Files fails to respond. It just freezes up. Now, Ubuntu both recognizes /Desktop as a file that exists, and also that it is not a directory. I had hoped that this approach would work, but since my system does not recognize /Desktop (I think this is the reason) it doesn't work.
I'm just looking to restore these files. I an see them in the Trash just fine, but I cannot get them back out. Thanks for any help!
