Knime Python bundle not working

Hey @steffen_KNIME @mlauber71 @knime ,
I am running into the same issue mentioned above. (I am working on win-64)
Excerpt:

Could not lock the environment for platform linux-64
...
 STDOUT:
{
    "solver_problems": [
        "unsupported request",
        "unsupported request"
    ],
    "success": false
}

    STDERR:
critical libmamba Could not solve for environment specs

As part of troubleshooting I looked into the bundling environment created with conda create -n knime-ext-bundling -c knime -c conda-forge knime-extension-bundling=5.3
I saw that the python version in this env is: 3.9
Upon trying to upgrade it to 3.11.9 I get the following error message:

This seems to be the issue for me (… i guess?)

I tried to create a new bundling environment with conda create -n knime-ext-bundling -c knime -c conda-forge knime-extension-bundling=5.3 python=3.11 … but still the same message

My environment.yml looks like this and was created with conda env export --from-history | findstr -v “prefix” > environment.yaml
