Error on importing KNIME workflow into Local Workspace

Hi KNIME Team,

I had been using KNIME v5.2.1 since 13 Feb 2024 morning until 3pm. Suddenly, KNIME UI has stopped due to an error. Thereafter, all the workflows saved in the Local Workspace was not visible.

I had searched the KNIME Forum for similar queries, but I still could not figured out how to recover the workflows in my Local Workspace.

I had uninstalled the KNIME application and restart my laptop at 6:17pm. At 7:51pm, I re-installed the KNIME application, I could not import workflows into the Local Workspace or load the previously saved workflows from my C:\Users\snow_\knime-workspace.

I have attached the KNIME log and some error log screenshots.

Greatly appreciate your advice.
