Issues with Google BigQuery nodes installation

Hi, I want to use the KNIME Google BigQuery nodes, but they are not showing up in the node repository.

It says they are already installed, so I go to KNIME/About and find Google BigQuery and uninstall the nodes, restart KNIME, then go and reinstall the Google BigQuery nodes, restart again, and they are still not showing up in the node repository.

If I load a workflow from a colleague with the Google BigQuery Connector node present, it is in a red hashed image, and it complains the nodes are not installed, launches a window to install them (v5.3), and then does not continue further, because the error says they are already installed.

I am on KNIME 5.3, on a MacBook (14.5 MacOS) using Apple Silicon.

Any help would be appreciated.

Thanks

Simon.
