The same problem, I tried to load a file from these variations, and I'm receiving the same error: 

csv_file_path = "/FileStore/data-co-uk/data/raw/1920_E0.csv"
OR
csv_file_path = "/Workspace/Repos/felipedi@gmail.com/data-co-uk/data/raw/1920_E0.csv"
OR
csv_file_path = "dbfs:/Workspace/Users/felipedi@gmail.com/data-co-uk/data/raw/1920_E0.csv"

and received it:
Public DBFS root is disabled. Access is denied on path: /FileStore/data-co-uk/data/raw/1920_E0.csv
