Delayed Layout Editor Opening Issue in KNIME Version 5.3.0

I’m using KNIME version 5.3.0 and I’m experiencing a strange issue. Whenever I try to open the layout editor for a new component for the first time, the entire screen freezes for a couple of minutes before the editor panel finally opens. This only happens the first time - after it’s loaded, I can use it without any issues. I’m not sure why it takes 3-4 minutes to load the first time. Can anyone help me with this?
