Knime 5.1.0 - Repository is empty in Modern UI and workflow from Knime 4 does not open in new int...

Dear Knime Support,

I am writing to report two issues that I am experiencing with Knime 5.1.0.

First, the Repository area is empty in the Modern UI interface. There are no nodes visible and searchable. I have tried reinstalling Knime and Modern UI extension several times, but the problem persists.

Second, workflows created in Knime 4 do not open in the Modern UI interface.

I have tried reinstalling Knime several times, but the issue has not been resolved.

I would appreciate any help you can provide in resolving these issues.

Thank you for your time and attention to this matter.

Sincerely,
