How to deal with freezes and core dumps

Support Snap/Flatpak
1

A day ago, my system froze when I was running Android Studio. After almost half an hour, Gnome restarted and things started working again.

While trying to figure out why this might have happened and what I can do to stop this happening, I found about coredumpctl.

This is the output of coredumpctl command: (I disable core dumps, thinking that it might be slowing down the OS in case of crash)

So, my questions are:

  1. what can I do so that this does not happen again and,
  2. where should I report these issues – to Flatpak team (in case of the software packages installed as Flatpak, in this case, Android Studio and Geary) or to maintainers of the respective software?
