Hi, in 5.8 (CUI) I opened a workflow which triggered the prompt to search for missing extensions. Whilst they were found a first hidden modal “Checking Link Updates Return Seasonality [NODE ADDRESS]” was hidden but blocking access to the UI. I could click cancel but nothing happened thereafter. After switching back and forth it became visible but the UI remianed inaccessiuble requirering me to kill the process. ![image](https://forum-cdn.knime.com/uploads/default/original/3X/3/2/322d5cc645c67c3b89e9a31d7d5bc2d656286259.png) Here is the log and the thread dump: [.log.txt](https://forum.knime.com/uploads/short-url/aWWRiKdKki4TzGRaSVHshENEfD4.txt) (24.3 KB) [threaddump-1762152097601.tdump.txt](https://forum.knime.com/uploads/short-url/uKgmegtGC57SyDzO1dx6Y1u4oVR.txt) (71.4 KB) PS: Here are the errors from the inaccessible modal ```auto Some Node Link Updates failed Unable to check for update of "Report Setup 3:1471:0:2000"; can't read LOCAL: Report Setup (/_Workflows/Report Setup) Unable to check for update of "Report Setup 3:1497:0:2000"; can't read LOCAL: Report Setup (/_Workflows/Report Setup) Unable to check for update of "Report Setup 3:1498:0:2000"; can't read LOCAL: Report Setup (/_Workflows/Report Setup) Unable to check for update of "Report Setup 3:1578:0:2000"; can't read LOCAL: Report Setup (/_Workflows/Report Setup) Unable to check for update of "Report Setup 3:1579:0:2000"; can't read LOCAL: Report Setup (/_Workflows/Report Setup) Unable to check for update of "Report Setup 3:1580:0:2000"; can't read LOCAL: Report Setup (/_Workflows/Report Setup) Unable to check for update of "Report Setup 3:1581:0:2000"; can't read LOCAL: Report Setup (/_Workflows/Report Setup) Unable to check for update of "Report Setup 3:1582:0:2000"; can't read LOCAL: Report Setup (/_Workflows/Report Setup) Unable to check for update of "Report Setup 3:1583:0:2000"; can't read LOCAL: Report Setup (/_Workflows/Report Setup) ``` Best Mike ---

We share them out of our private KNIME HUB instance. Those templates will often have Components which we manage, plus Extensions. For example, in this case a Component that helps create a secret for the user. But when the user “Drag-and-Drop” from the KNIME HUB, the interface is being locked up.
