Failed to open (load module) desktop app

[yalin]

Hi,
I'm using Pop!_OS 22.04 LTS
I downloaded Raindrop from Snapcraft

When I want to run Raindrop, I get this error;

Failed to load module "appmenu-gtk-module"
SNAP env is defined, updater is disabled
[1123/082910.409279:ERROR:scoped_ptrace_attach.cc(27)] ptrace: Operation not permitted (1)
Trace/breakpoint trap (core dumped)

Then, I used the commands below in terms of solving the issue;

sudo apt-get install appmenu-gtk2-module appmenu-gtk3-module
sudo apt-get install --reinstall libcanberra-gtk-module

They worked last week and solved the issue, but now it is happening again.
I can not open the desktop app.

Today it showed the similar error but the program started;

Failed to load module "appmenu-gtk-module"
SNAP env is defined, updater is disabled
Error org.freedesktop.DBus.Error.Failed: cannot set "default-url-scheme-handler" subproperty "rnio" setting to invalid value "Raindrop.io.desktop"
checkForUpdatesAndNotify called, downloadPromise is null

I am on Ubuntu 20.04.5 and I am getting a similar error. The app is stuck at Signin page. Redirects to browser for signin and after signing in nothing changes.
The terminal messages are as follows:

I have appmenu-gtk-module installed. Skype works and spews out similar messages.
