As mentioned in the forum thread opencv doesn't seem to be the problem, it is incorrectly reported by asm4. The actual problem is with pillow that has removed qt5 support in version 10.0

uploaded pillow 9.5 pacakges to conda: https://anaconda.org/freecad/pillow/files
new bundles should be up shortly and I confirmed at least the appimage works:
