Hello community, When I log in KNIME my local workspace is empty and the workflow I created is not visible. [afbeelding] Among other I saw the following error message in the console window. The error message is to cryptic to understand any word of it. I have installed KNIME 5.1 on laptop running windows Editie Windows 10 Enterprise, Version 22H2, Installationdate 23-‎11-‎2022, Build 19045.3448 , Windows Feature Experience Pack 1000.19044.1000.0 Error message: ERROR PurePythonNodeSetFactory Failed to parse Python node extension at path ‘C:\Program Files\KNIME51....\Users\875009.eclipse\524691596_win32_win32_x86_64\plugins\graudata.mdh_extension_1.0.0.202308210900\src\main\python’.
