Description ingenarelitems 2025-02-10 17:13:55 UTC
when trying to use quickeffects, or any kind of effects in blender, it crashes with this:

```
Fatal Python error: PyImport_AppendInittab: PyImport_AppendInittab() may not be called after Py_Initialize()

```

the problem is that this is not an issue with blender, but how python 3.12 works.

i just finished building blender with 3.11, and i can personally confirm that using python 3.11 fixes everything

and yes, it's a year old problem, so it's best if python 3.12 with blender got dropped.
