Fenics Installation problem using source

I am following this post Installing Fenics on Windows - #26 by Calva (link given by you in this message thread). I have installed the vcxsrv .exe file given by you in my windows system. I have edited my bashrc file. Still it is showing some error:

fenics@DESKTOP-CVH2BNB:~$ python3 demo_poisson.py
WARNING:py.warnings:/home/fenics/spack/opt/spack/linux-ubuntu20.04-skylake/gcc-9.4.0/python-3.9.13-pcu4sw73ldnrq56zpsmhzdotodg5rh6i/lib/python3.9/site-packages/pyvista/plotting/plotting.py:115: UserWarning:

PyVista will likely segfault when rendering.

Try starting a virtual frame buffer with xvfb, or using
pyvista.start_xvfb()

MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode 59.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.

I am unable to do the step:
*Check the ‘disable access control’ checkbox in the VcXsrv config.
Can you please tell me how to do that?
