I encounter the same error message when I try to edit Python Script node and it doesn’t allow me to edit the script. It’s a real struggle because I’m having a lot of Python scripts in some of my workflows and I am currently blocked.

With the support of my organization’s IT department, the solution was to uninstall KNIME 5.5 and install it from scratch. I recommend backing up your workspace to a ZIP file, just in case any issues arise. I have Python nodes too, everything is working ok.

Thank you! I’ve downgraded to 5.4 and things works fine for me know.

@lucdelon @ymeknassi Sorry for the inconvenience! You encountered a nasty upgrade bug that snuck past QA into the release. We found a fix yesterday evening and upgrades from 5.4 to 5.5 should work smoothly now. More details here: Updating to 5.5.0 causes blank page after restart - #16 by wiswedel
