Viscera Script Not Launching Steam?

I’m trying to install Viscera Cleanup Detail using this install script (Script) on my sister’s computer for her but when I try running the script on hers it doesn’t launch Steam. I tried doing it on mine as its the same OS and such to see if it worked and it opens on mine but not hers.
On both, when I click the install script link and open it in Lutris it opens up a dialogue for selecting which version to install. If I continue and then hit install on my computer launches steam for me to log in and install the game but hers just sits there endlessly on the ‘Installing game data’ dialogue without even trying to open Steam.
