2019/02/22 15:58:35 ERROR - neoload.Gui: An error occurred while preparing the scenario for testing. For more information, see the log file.
As you can see the error is "Access is denied". You may have an anti-virus that is checking the NeoLoad files or even an issue due to the fact that your NeoLoad project folder is directly under C: drive.
Could you try to move your project into your Documents folder in case you have some system constraints?
