Blender autosave files shouldn't be saved to the user's /run folder as it's very restricted with regards to available space. Once it's filled other programs are likely to fail to start.

Restricted filesystem access

As it stood, Bforartists had unrestricted access to the host system.
This is unacceptable, so now Bforartists only has access to home and
/tmp.

/tmp is needed for autosaves. It was found in
flathub/org.blender.Blender#122 that using
Flatpak's remapped tmp directory causes issues with other Flatpaks not
starting.

Blend files get massive, especially for multiple autosaves, so access to
/tmp (which is cleared on reboot) is important
