It is hard to tell what is going on from just that error message. Is there anything unusual about the way you built your snap? Can you post a copy of your snapcraft.yaml (either a link to a repository, or using paste.ubuntu.com should do)?

We have found the solution ourself. Solution was adding pyqt5 under staging packages
thanks to @jamesh for responding

Based on your other thread, were you installing the snap with --classic? That might explain the error you saw, if your app was linking to a mix of Qt libraries from your snap and Qt libraries from the host system.

Your snapcraft.yaml just says devmode, which is effectively strict mode confinement without the AppArmor security checks being enforced. That is quite different to the environment a snap runs in when classic confinement is chosen.

It was in devmode we are now requesting for classic confinment after application started working
