Plex Flatpak doesn't always open when clicking the dock icon

[DavidRedstone]

Plex Flatpak doesn't always open when clicking the dock icon. It usually works the second time, or the third.
Sometimes it looks like it is about to open but then quits.

I'm on Ubuntu 20.04, Gnome 3.36.3

Same problem, but after random try it starts for me. (w/ intel gpu)
But every instance is in the process list, in the background. They can close manually only with name bwrap --args 39 plexmediaplayer

Config

It is a new Thinkpad, w/ faultless memory and processor. I checked it. And every program is up-to-date.

Ubuntu 20.10
Intel Core i5-8265U

Hi. Could you check if the issue still exists with the latest Flatpak package?

flatpak update
flatpak run tv.plex.PlexMediaPlayer
