[ARM Stable Update] 2021-09-28 - Firefox, Thunderbird, LibreOffice, Electron, Element and Kernels

Hello,
Sorry to comeback with that, but 3D slicers like Cura or PrusaSlicer still cannot launch. They used to work like a charm, but since about this summer, I tried what I could (not much) to fix it. I got the same problem as here described
[ray@pi4 ~]$ cura
Traceback (most recent call last):
File “/usr/bin/cura”, line 25, in
import pynest2d # @UnusedImport
ValueError: PyCapsule_GetPointer called with incorrect name
In

Any ideas?
Thank you
