Views: Configuration Dialog and Interactive views empty in 5.3

After installing 5.3, view nodes from the Views group in the node repository have an empty Configuration Dialog and show an empty interactive view when executed. This happens in both existing Workflows and new ones.

Statistics views from the Analytics node repository group seem to work fine.

I have both an upgraded Knime installation (from 5.2) and a new install. It happens for both. I’ve also tried using a new workspace. Still doesn’t work.

This is on Windows 11.

Is there some settings/configuration file I need to clear? What could cause this?
