Task Scheduler return code 2147942401.

Question

Hello.
I use this scheduled task for years and it always worked fine. Something weird happened a few weeks ago.
This task executes .bat file which launch python script.
It runs as administrator.
A few weeks ago it started fail with return code 2147942401. Note: if I execute it manually by click on 'Run' or from prompt it always succeed.
The are a lot of articles related to this error and I've tried all of it but it still failed. Hence I'm confused what happened.
Here are the things I've tried to change and none of it fixed the issue:

1. Change options on 'General' Tab
2. Change time of execution. Note: it's scheduled to run daily once but I've tried to set it to run hourly for the day and it succeeded only 2-3 times
3. Change 'Action' Tab parameters
4. Create a new Task
5. many other things but none of it worked.
   Do you have any clue what else could cause the issue to fail the Task that worked for years?
   Thanks

Unfortunately, Windows Task Scheduler is not supported in the Microsoft Q&A. Request you to raise the question here https://answers.microsoft.com/ where there are active answering on these topics.

Having, said that the error code translates to hex code 0x8007001 and came across this article which may help you further. In case you have further query, you may reach out to the above mentioned forum.

It has been many hours very frustrated as to why my console app works fine running interactively but not when it runs in Window Task Scheduler.

I got this in the history for the task '...action "C:\Windows\SYSTEM32\cmd.exe" with return code 2147942401'

The solution  Do NOT put the full file path in the program/script textbox. Instead put only the name of the bat file there. Put the path to the bat file in the Start in (Optional) field.
