How to run VNC as a System Service on 64-bit Arm?

systemd vnc systemctl tightvnc vncviewer
                          I'm following this guide  to setup VNC server in my Ubuntu arm64 machine (specifically, armbian  64-bit). There's one problem I found with it so far.

When I start the VNC server using vncserver :1 -localhost no command, it didn't work and crashed after I tried to access the session from a VNC client.

But, when I tried with LD_PRELOAD=/lib/aarch64-linux-gnu/libgcc_s.so.1 vncserver :1 -localhost no command I found here , it's started to work.

Now I want to manage this as system service using systemctl command. So, I have this unit file:

    [Unit]
    Description=Start TightVNC server at startup
    After=syslog.target network.target
    
    [Service]
    Type=forking
    User=zulh
    Group=zulh
    WorkingDirectory=/home/zulh
    
    PIDFile=/home/zulh/.vnc/%H:%i.pid
    ExecStartPre=-/usr/bin/vncserver -kill :%i > /dev/null 2>&1
    ExecStart="LD_PRELOAD=/lib/aarch64-linux-gnu/libgcc_s.so.1 /usr/bin/vncserver -depth 24 -geometry 1280x800 -localhost no :%i"
    ExecStop=/usr/bin/vncserver -kill :%i
    
    [Install]
    WantedBy=multi-user.target

Now when I ran...

    $ sudo systemctl daemon-reload
    $ sudo systemctl enable vncserver@1.service
    $ vncserver -kill :1
    $ sudo systemctl start vncserver@1

...I got this:

    $ sudo systemctl status vncserver@1
    ● vncserver@1.service - Start TightVNC server at startup
         Loaded: bad-setting (Reason: Unit vncserver@1.service has a bad unit file setting.)

    Apr 16 17:38:00 armbian systemd[1] : vncserver@1.service: Unit configuration has fatal error, unit will not be started.

What should I do to fix this?
