Migrated to core22 and used kde-neon extension, but need help with configure

[soumyaDghosh]

I have tried to migrate the snap to core22 and make use of kde-neon extension. It builds up, but when I try to install that snap it shows me a configure hook error. I guess a little more digging into this and we will have the zoom-snap more stable and ready for core22 (& core24 later on).
This is the error log:

error: cannot perform the following tasks:
- Run configure hook of "zoom-client" snap if present (run hook "configure": 
-----
update.go:85: cannot change mount namespace according to change mount (/var/lib/snapd/hostfs/boot /boot none bind,ro 0 0): permission denied
cannot update snap namespace: not a directory
snap-update-ns failed with code 1
-----)

This is the snapcraft.yaml
