White Screen of Death

In the last few weeks I have been experiencing the White Screen of Death from KNIME. Basically the screen goes white only showing the window edges and top bar. When I try to close the window it will pop up a window asking to save a list of changed workflows but when you hit Yes nothing happens. If you try the same and say No nothing happens. So I have to use the Windows 11 task manager to kill KNIME.

Obviously this sucks because I loose all my work. In another thread I have asked to give the Classic UI a save on run option but that has not yet happened.

When I look at the knime.log file nothing stands out except that I use and store shared components on Knime Hub (obviously because I want to share them with my collegues)

So I see log items like “Could not load template for “Custom Node 3:3506” - it links to “knime://My-KNIME-Hub/24FT3EBFfMpIiMqh” but it could not be accessed: Cannot resolve to local file: resource ‘/24FT3EBFfMpIiMqh’ does not exist”

If I were to guess what causes the crashes (because the log does not give other information) is because it cannot get to a component shared from the Hub. Many of the workflows are stored locally but use Hub components.
