$Particle View 01 activates as I operate the above script, but I can not update the particle on the viewport. Also, it can not be updated on the FOR loop.

However, if I operate them separately, it is updated automatically.

So my question is that what should I do to update the viewport on the script as above or the FOR loop?

$Particle View 01.Enable_particles = true
