Default Ubuntu Desktop with TightVnc and Windows Linux Subsystem

I have successfully installed WLS (ubuntu 18) on windows 10 machine. I want to access its UI features using TightVnc. With default settings the .vnc/xstartup contains the following lines

xrdb $HOME/.Xresourcesxsetroot -solid grey#x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop"&#x-window-manager &# Fix to make GNOME workexport XKL_XMODMAP_DISABLE=1/etc/X11/Xsession

and I can connect to it using Tight vnc viewer from windows but the UI looks likeBut, I want to use the default desktop that ships with Ubuntu 18. I installed gnome and changed xstartup file to the following (suggested by someone on the web)

#!/bin/sh#Uncommment this line if using Gnome and your keyboard mappings are incorrect.#export XKL_XMODMAP_DISABLE=1# Load X resources (if any)if [ -r "$HOME/.Xresources" ]then        xrdb "$HOME/.Xresources"fignome-session --disable-acceleration-check --session=ubuntu &

But when I start vncserver after making these changes, I am able to connect but it shows a grey screen with no visual controls likePlease note that I had no .Xresources file on my machine so I created an empty one manually but it made no difference. Below is the output of ls /usr/share/xsessions

I can see some errors in .vnc/CS-63341DT:5.log file. Below are the contents of this file
