Windows 10: Task Scheduler Error - The Specified Account is not Valid

Hi, My windows 10 machine is about 3 years old. When I try to edit the task to change the start time, I get the error "The Specified Account is not Valid". when I click Finish. The task was originally created when I purchased the machine, about 3 years ago. It runs fine with no errors. But any time I try to edit it, I receive the same error on finish. I tried to create a new task, get the same error. I tried to export, rename, edit and import, same error on Finish. I also tryied to run Task Scheduler "as adiministrator", same error thoughCan anyone please tell me how to fix this - I can no

:)

 

Task Scheduler Error: One or more specified arguments not valid


What is wrong with Task Scheduler on Windows 10?

Here is where I add my task:

 

Windows Task Scheduler Error (one or more of the specified arguments are not valid)

I'm having a rough go trying to use Task Scheduler to schedule tasks.

I had the system working for a 6am program for about two weeks. I decided that I wanted to shift users to a new account about two weeks ago, and my task hasn't run properly since. I get this in general from the task. I have both the latest draft of the task
and the original one that worked before switching accounts:

When editing the task, every time I get a "one or more of the specified arguments are not valid" error message. I think it has to do with the account I'm running it from. I've looked at other solutions to this issue using the SYSTEM account and switching
to 'run whether the user is logged on or not' but that's greyed out for me:

I have not tried running this through a different account since I removed the old one. I looked through a bunch of suggestions from

here but no luck.

Any new suggestions? Is there a step I may have missed in creating the new account (Atlas) to give it proper permissions?

Here are the screenshots of my setup:
