Custome Text Classification - Project assets file is invalid for your project error

Hello,
I have a bunch of text files I have uploaded to blob storage and am trying to make a new Custom Text Classification Project.
The text files were used in another project. So I uploaded them to my blob storage.
But when trying to enter the project details I get stopped here:
"Project assets file is invalid for your project Train_Project1. It was either deleted or corrupted. Import new labels to your project or create a new one."
I am not sure what the asset file is.
A .json file did appear in the Blob I did not create.
Here is what it looks like:
{"intentNames":["None"],"entityNames":[],"entityHierarchySeparator":null,"documents":null}
Thoughts?
If more info is needed please ask!
Thanks,
