KNIME 5.3 : Environment creation failed: Packages not available from channels.

I am trying to install a Conda environment for phyton that contains all packages required for KNIME-Keras integration. I have KNIME 5.3 and I am using macOS15.

Not sure the image is uploaded. when attempting to create a new Conda environment I am getting the error that packages are not available from current channels:

https://conda.anaconda.org/conda-forge-osx-arm64

Any help in resolving this is appreciated. Thank you very much
