Android app converted from a react app via capacitor starts up really slowly

I have build an App using React.

I have converted it to an Android app using capacitor.

The app, running on a Nokia G10, consistently takes over 30 seconds to startup.

Other similar apps that I have installed on the Nokia G10 starts up much faster.

The splash screen does get displayed quickly though.

I am starting this thread looking for a fix.

Please ask me anything.

Thanks
