keepassxc snap crashes on start with "ERROR: not connected to the kde-frameworks-5-qt-5-15-3-core20 content interface" after snapd auto refresh package from 2.6.6 to 2.7.0

[rfc]

Operating System: Ubuntu 21.10 (64-bit)
Desktop Env: Gnome 40.4.0
Windowing System: Wayland

I previously installed latest stable version of keepassxc snap package, which was 2.6.6

keepassxc snap worked, a few weeks passed

keepassxc maintainers released new stable version of keepassxc snap package, 2.7.0

ubuntu's snapd appears to have auto refreshed and upgraded keepassxc from 2.6.6 to 2.7.0

keepassxc no longer displays GUI, when launched immediately shows error message:
ERROR: not connected to the kde-frameworks-5-qt-5-15-3-core20 content interface.

Keepassxc maintainer suggests this may be an ubuntu or snapd problem.

Speculation about possible cause of issue:

Is is possible that when auto refreshing snaps to new stable version, the auto refresh logic fails to install new extension dependencies (e.g. kde-neon) ?

It is perhaps possible that there may be an issue with how keepassxc snap package 2.7.0 declares runtime dependencies. I don't know enough about keepassxc, snap packaging to dig further.
