Alteryx stuck on 0% reading input SAS file

[Ruby2]

Hi.  First time posting so my apologies if I am leaving out critical info.  I am on 2019.4.8.   I have been working on a workflow for a week or two with no issues but since last week it will no longer read my SAS input file.  It doesn't progress past the input icon which sits at 0%.  It has sat there for an hour before I eventually have to cancel.   The SAS file is in the location and available.  I can't find anything in discussions or help on this. Does anyone have any idea?  Thank you.

I found the problem.  The file is too large and is on a network drive that is running slow.
