Patch at: https://gitlab.archlinux.org/archlinux/packaging/packages/blender/-/blob/44a846df45bbc7437c464ac68290871523f2489c/blender-4.11-mantaflow-python-3.12.patch was tested and works. Just modified the spec and recompiled the source rpm at https://koji.fedoraproject.org/koji/buildinfo?buildID=2575769 and installed the resulting rpm. I'm using fedora 39, but I believe this affects more recent releases too. === Bug is that Python 3.12 seems to have introduced stricter checking for PyImport_AppendInittab() and when attempting to use fluids in blender, it immediately crashes with: Fatal Python error: PyImport_AppendInittab: PyImport_AppendInittab() may not be called after Py_Initialize() Python runtime state: initialized Applying the patch above fixes the problem. Hope that helps Reproducible: Always Steps to Reproduce: 1. Run blender 4 2. Attempt to use fluids (eg: Object > Quick Effects > Quick Liquid) 3. Crash
