Cannot Export THIS File to THIS Folder

[Amanda33269831f4ys]

So, I have a folder with PSDs in it. No problem. I go to export (save for web) the PSDs to another folder within that folder, and I receive an error: "Could not complete this operation. The system cannot find the path specified." I'm using a plug-in to export, so I try manually exporting them: "Could not write the file. An unknown error has occurred." 

So, I tried troubleshooting. I tried exporting the files to another destination. Works fine. I tried exporting other files to this destination. Works fine. I tried moving (not copying) the folder, then creating a new folder with the same name in the previous destination and putting the files in it. Can't export to this folder either.

Users/Documents/Projects/Project1/Exports/JPG

--Cannot export from Project1 to JPG

Users/Documents/Projects/Project2/Exports/JPG

--Can export just fine with and without the plug-in

Users/Desktop/Project1/Exports/JPG

--Can export just fine

I've updated Photoshop and I've restarted it.

Apparently, I just can't export these files to this destination.  I know there are work arounds I could try, but at this point I need to know what's happening in case it happens again.

Update: I also can't export the files from Desktop/Project1 to Projects/Project1, but I can still export other files from other folders to Projects/Project1.

Another update: I have figured out that the issue is the path length. However, it is still an Adobe issue because I have long path names enabled on my computer. (An option available on Windows 10 and later.) I'm having to export to my desktop and then copy/paste the files into the correct folder.
