Particle Editor stopped working after hanging and reopening

It happened after a while of using Defold. After Particle Editor of a particlefx looked to be hanged up for a while (not responding to mouse clicks, but rest of the Editor was working) I closed that editor and opened the same particlefx again. The Error window appeared and I was seeing nothing (as above on the screenshot.

Closing and reopening the Particle Editor does not help.

Closing and reopening the project solves the issue.
