I can see the error message, but the explosion works fine.

Python: Traceback (most recent call last):

Only part of the explosion works, everything after mat.shadow_method = 'HASHED' in object_quick_effects.py does not work, including setting the material correct, setting the velocity, etc. I believe it's due to Material.shadow_method being removed from the API(842c2b2c6a).

Below is default cube with quick explosion at frame 1.

They should be the same under the same settings

I'm not really into effects and particles, are these results random or should they be the same every time you add this effect?

Marking as confirmed and looking into creating a PR to fix it.
