Upon table export to CSV or "load more", one user gets an error "Read access denied....."

Upon table export to CSV, if “load all records” is selected, a user gets an error “Read access denied for CustomObject__C, controller action method may not execute”. The user is assinged to a profile that has view all permissions for that object. The user can see the records in the table, but if load more or export buttons are clicked. They get this error message. Anyone have any ideas?

Other users in the same profile / perm set collection are able to export successfully?  That is very strange. 

Any ideas on what may be causing this. User profile has Modify all level permission to the object.

I am completely stuck on this. I have two users with Salesforce licenses assigned to the same profile and the same role and have the same permission sets but one can use the “load more” button and the other gets the error.
