Telegram-desktop can't attach any file: can't see any file in attach dialog, nor open any drag-n-dropped file.
Telegram installed correctly, I'm not asking how to install it.
I installed Telegram Desktop via snap.
sudo apt install snapd
sudo snap install telegram-desktop
When I open file browser, it shows empty folders. When I drag files into app window, it shows a popup can't attach empty file <filename>.
In htop, application Telegram has my own user. Everything seems to work correctly except for attachments. Here's what it prints to stdout/stderr in shell:
Qt: Session management error: None of the authentication protocols specified are supported
Gtk-Message: Failed to load module "appmenu-gtk-module"
Gtk-Message: Failed to load module "canberra-gtk-module"

How can this be fixed?
