qt couldn't connect network

After installation, I found it completely unusable. I then discovered the following error(s). I've already updated to the latest version.

Nvidia strikes back found this: FreeTubeApp/FreeTube#6158

I don't have any remotely modern nvidia card to reproduce

External Graphics Driver issue, the flatpak is sometimes unusable on nvidia depending on flatpak specfic own driver copy.

Use this in google search

to get more information about the failure.

All other information of your log is just non fatal noise.
