Why does the task scheduler run the task twice?

Question

Windows

Hello.
I have Windows. The task scheduler has a task to launch an exe file.
The problem is that the task runs twice in a row, although it should only run once.
I tried to google, there are similar questions, the answers are not: link
There is a go, why can this be?
Jackdaws "repeat launch if" are definitely not worth it.

Answer 1

Check the box - "If already running - do not start a new instance."
