This gnome-shell suicide is the only explanation I can see:
Sep 18 15:01:22 shanu-Inspiron-15-3511 gnome-shell[16721]: Connection to
xwayland lost
Sep 18 15:01:22 shanu-Inspiron-15-3511 gnome-shell[16721]: Xwayland terminated,
exiting since it was mandatory
Sep 18 15:01:22 shanu-Inspiron-15-3511 gnome-shell[16721]: JS ERROR:
Gio.IOErrorEnum: Xwayland exited unexpectedly
@resource:///org/gnome/shell/ui/init.js:21:20
Sep 18 15:01:22 shanu-Inspiron-15-3511 gnome-shell[16721]: Execution of main.js
threw exception: Module resource:///org/gnome/shell/ui/init.js threw an
exception
Also pid 16721 is the correct session (the second last gnome-shell
instance in the log).
So we're probably looking for an Xwayland crash but I'm not seeing any
crash reports. Do you have any new files in /var/crash/ ?
