The message history is display by the ":messages" command. Error E163
probably means that your session file issues a ":next" command with an
argument list improperly set.

the "normal" way to start a session file would be

gvim -S '$VIM/vimfiles/sessions/RW.ses'

except that the "normal" extension for a session file is .vim, because
it is a Vim script. (If the name of the session file is Session.vim in
the $HOME directory, you can omit the name altogether, both in
:mksession and after -S )

If the above works, try adding (untested)

set nohidden
new
only
if winnr('$') > 1
echohl Error
echomsg 'Some buffers cannot be abandoned!'
echohl NONE
echoerr 'Please :quit! or :exit them'
return -1
endif

before the :exe line in your LoadSession function. (When starting Vim
with -S, the session file is sourced with only an empty [NoName] buffer
loaded, and that buffer displayed in the only window. That's what the
session file expects to find when it starts.)

Best regards,
Tony.
