Hello !
I noticed a conflict between PyOpenColorIO 2.4.2 and PyQt6.
Let me detail the issue, when importing PyOpenColorIO after PyQT6, python crashes. But when importing PyOpenColorIO first, it works.
Minimal reproductible example :
( python 3.13 )
from PyQt6 import QtCore
import PyOpenColorIO as OCIO
The same code with PyOpenColorIO 2.3.# and python 3.12.# works like a charm.
