KNIME Analytics Platform UI Frozen

My KAP Classic UI is currently completely locked up and every time I click on it, the only response is a sound/tone.

I was using the stream manipulation node in a workflow where another branch was looping and writing files into the local workspace when the configuration window suddenly disappeared and I can’t find it anywhere.

I don’t want to lose my work - any suggestions? I am using Windows 10

The last message in the log file:
“ENTRY org.eclipse.ui 4 0 2024-07-03 13:14:35.212
!MESSAGE Unhandled event loop exception
java.lang.NullPointerException: Cannot invoke “org.eclipse.swt.widgets.Shell.setCursor(” because the return value of “org.knime.workbench.ui.wrapper.WrappedNodeDialog.getShell()” is null”

The only hotkey that seemed to work was “save all open workflows”…and after restarting the computer, everything seems back to normal


Hey @RedJungleBear,

If it happens again, let us know so we can look into it!
