Tried starting the app from terminal which helped me identify the issue, these were the errors
Remote error from secret service: org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.secrets was not provided by any .service files
(node:6205) UnhandledPromiseRejectionWarning: Error: The name org.freedesktop.secrets was not provided by any .service files

I can confirm that `sudo apt install gnome-keyring` solves the problem on KDE. Looks like the problem is with `node-keytar`. Thanks for the support and pointers till now
Note :- problem solved by installing `sudo apt install gnome-keyring` on debian 10 kde
