I've run an strace on `startx` and it throws quite a few errors for me: https://i.imgur.com/eDJSri3.png

When I however install `gdm` and launch `Pantheon` from it I crashes once and I can work just fine then: https://i.imgur.com/0a9HW0x.png

Edit:
Could it be that some Gnome-Settings-Daemons are not running because of wrong Paths?

https://github.com/elementary/session-settings/blob/master/autostart/gsd/org.gnome.SettingsDaemon.Keyboard-pantheon.desktop

`/usr/lib/gnome-settings-daemon/gsd-keyboard`

We ship them in gnome-settings-daemon-3.34.1_2  `/usr/libexec/gsd-keyboard`.

Edit2: 
Yep this seem to be the cause. If some components can't start, gnome considers the session to be crashed: https://bbs.archlinux.org/viewtopic.php?pid=1874971#p1874971
