KNIME Dark Mode not working

Dear Knime Enthusiastic!!

Hope you are doing well.

I am facing an issue wherein the preferences of appearances is not being saved. I tried to change the theme to Dark Mode and once I apply the changes and restart the app, it goes back to the default. I have tried to reinstall and check in other system but the same issue persists. This issue i am facing since last 3 months.

My current version- 4.4.1

Thanks,

Ravi
