Short description of error
When rendering the explode effect there are random glitch frames where the geometry is messed up.

Exact steps for others to reproduce the error
I believe this is related to non-native geometry.
I imported an FBX from 3dsMax. Came into Blender no problem and renders fine.

Applied 'Explode' effect and baked particles but the render has random frames of messed up geometry.

See attached file...

I can confirm, it has render artifacts of frame 21 for example:

It works in the viewport preview though.

Please see:
https://docs.blender.org/manual/en/dev/render/cycles/object_settings/object_data.html#render-cycles-settings-object-motion-blur

An object modifier setup that changes mesh topology over time can not render deformation motion blur correctly. Deformation blur should be disabled for such objects.
Common examples of this are animated Booleans, Deformation before Edge Split, Remesh, Skin or Decimate modifiers.
