Read CSV Randomly Stopped Working

So I have been running a program for months that reads a CSV and turns it into a dictionary. I have never had a problem until today when I started receiving this error for any csv file I try to navigate to:

{
“message”: “Invoke ProcessNewHireCSVtoDictionary workflow: Read CSV : Could not load file or assembly 'CsvHelper, or one of its dependencies. The system cannot find the file specified.”
}

Does anybody have any idea why this would begin to happen? Thanks.

Hi.

does this help?

Yes it did. Thank you very much.
