Does anyone has received this message sometime?
I have not seen that. I notice you're editing a script. Is there a web viewer in the layout under your script workspace that might have some JS running in it?
Do you have idea how to fix it?
I'd have to see the code. But in order for it to NOT run while you're doing development, go into layout mode.
Or use a script to load the web viewer with the HTML / JS at runtime.
