Video does not play; I only see a static screen. No play button

I installed the Flatpak version, and video does not play at all. I started it from terminal to see error messages, and the message was like

** (process:117069): WARNING **: 07:15:08.231: Error writing credentials to socket: Error sending message: Broken pipe

Indeed, in the config directory, there was no dconf. Shouldn't it create a new one, if it does not exist?
