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. here are some relevant links: https://projects.blender.org/blender/blender/issues/129926 https://www.reddit.com/r/blenderhelp/comments/18zx8xp/blender_40_crashing_when_setting_an_object_to/?rdt=64527 https://forum.manjaro.org/t/in-manjaro-wynsdey-blender-4-1-1-crashes-python-error-pyimport-appendinittab/162387 https://gitlab.archlinux.org/archlinux/packaging/packages/blender/-/issues/18 https://gitlab.archlinux.org/archlinux/packaging/packages/blender/-/issues/1
Seems we should backport https://projects.blender.org/blender/blender/commit/1865de1c738a1a1ead520fbd38487815e13906e9.
