That error message is very clear. The filename you used is wrong.
There is no file named C:\Users\mauri\OneDrive\Desktop\Private\SAS\Data.csv in the current working directory of the Unix machine where SAS is running. Fully qualified filenames on Unix machines must start with the root node, the leading slash in the path mentioned in the error message.
First upload the file to the machine where SAS is running and then use the name as seen on that machine. Probably something like: /home/mauri/Data.csv
