Can't open launcher on linux

[sneakyswin]

I'm trying to run plutonium on my Elementary OS install using the following guide: https://forum.plutonium.pw/topic/8261/guide-how-to-run-black-ops-2-zombies-on-linux. The Lutris installer always got stuck somewhere, so I tried doing it manually with wine. I installed all the dependencies using the commands from the guide, and set up the .sh file as written. When I run it, I get the following error: https://pastebin.com/ezkfXFAe. It looks like an error with dotnet or something, but I installed it using the commands from the guide, so I don't know why it gives me that error.
