One of the causes of the issue was the assigned value for:

• PdfExport_SecondaryEnginePath
• PdfExport_SecondaryEngineArgsPattern

from WebSettings table while there are no Additional Web Servers in deployment. 
There is a possibility of an issue with permissions and other security settings of the environment that are preventing the execution of normal functionality.
