No idea. Given the other problems you were experiencing, including the XDG permissions error you reported, the issue may be system-specific. No one else is reporting it, and I cannot reproduce it.

My best suggestion is to start the TurboVNC Server without a window manager, by passing -noxstartup to /opt/TurboVNC/bin/vncserver. Then run the window manager command manually:

DISPLAY=:1 /etc/X11/Xsession "env GNOME_SHELL_SESSION_MODE=ubuntu /usr/bin/gnome-session --systemd --session=ubuntu"

That may reveal the source of the failure.

Scratch that. Ubuntu apparently logs the console output of the window manager to ~/.xsession-errors, so check that file for errors.

Resolved.
By reviewing file ~/.xsession-errors, it was found that there is an error in the format of file ~/.xsessionrc. Correct after modifying the format of file ~/.xsessionrc.
