Kivy Designer won't start?

Question

Python

Hello dear users!
The problem is this:
I installed the Kivy Framework, all the dependencies, the applications that are given in the examples, and the applications that I write myself, work with a bang.
But now, I recently learned about such a program as Kivy Designer. I installed all the dependencies for it, but it does not start, crashing with an error:

Fatal Python error: (pygame parachute) Segmentation Fault
