Disco Diffusion error

i tried to install Disco Diffusion inside the stable diffusion, but when i execute the the webui-user.bat, the cmd shows this message:

The file may be malicious, so the program is not going to read it.
You can skip this check with --disable-safe-unpickle commandline argument.

Does anyone know how to fix this problem
