Anki as flatpak cannot open file manager

Hi, I’m using Anki as a flatpak. I know that it’s in the repos, but due to some issues with that one, I switched to the flatpak version. The dev supports neither the repo version nor the flatpak though, he tells people to “make install” his precompiled binaries :slight_smile:

How to reproduce:

  1. Open Anki
  2. Open add-ons dialog (eg Ctrl + Shift + A)
  3. Select an add-on
  4. Click “View Files”

Expected result: The add-on directory will open in dolphin

Observed result: Nothing happens
