I based mine off this disintegration particle effect.
I originally tried to do this with my olaf figure but the particles were not emitting where I wanted so I switched to a cube.
Unfortunately, when exporting it hiding all my effects so I did a screen recording. The tutorial did mention that he had trouble with the particles with the newer version of blender so I figured it was that.
Here's what was rendered:
