With current master and your data, I get the following error :
Traceback (most recent call last):
File "/home/julien/work/QGIS/install_release-3_4_debug/share/qgis/python/plugins/processing/algs/qgis/VoronoiPolygons.py", line 133, in processAlgorithm
point = geom.asPoint()
TypeError: MultiPoint geometry cannot be converted to a point. Only Point types are permitted.
Which means you have to convert your data first using the treatment "multiparts to single parts", then it works.

Thank you for the guidance. It also works for me.
