Another gvim error (on windows)

Hello, when I try to install this plugin and start gvim 8.1 for windows (this is the default version downloaded from here: https://www.vim.org/download.php#pc)

I get the following error

VIM - Vi IMproved 8.1 (2018 May 18, compiled May 18 2018 18:36:07)
Unknown option argument: "--multiprocessing-fork"
More info with: "vim -h"

TIA
