This happens for me too.

Add Torus -> Add Tyflow -> Add Preset event -> Replace "Birth" with "Birth Surface" -> Change "Particle Birth" from "All Vertices" to "Selected Vertices" -> instant Crash
Oh and if i convert the object to a mesh first and actually select some vertices before change to "Selected Vertices", it does not crash. Unfortunately though, the particles are not spawned on the vertices but on the objects center.
