Compilation error on macOS

[turbo-archer]

Attempting to compile master/dev/v6.0.3 on macOS Ventura yields following compilation error:

..opennn/opennn/convolutional_layer.cpp:131: error: member reference base type 'opennn::type *' (aka 'float *') is not a structure or union
convolutional_layer.cpp:131:53: error: member reference base type 'opennn::type *' (aka 'float *') is not a structure or union
    const Index output_channel_number = combinations.dimension(2);

Any clues on fixing this?
