'Any CPU' Issue, can't target x86/x64

I’m having a bit of an issue getting Monogame going on Arch. I have Monodevelop 7.8.1, and have installed the latest Monogame using monogamesdk.run. When I create a new project using Monogame everything seems to populate correctly. However when I try to run the project I get the message:

Cannot open assembly ‘/home/wolfshirts/Projects/game/game/bin/DesktopGL/Any CPU/Debug/game.Desktop.exe’: No such file or directory.

I’m not sure what is causing the issue. I also cannot configure my build to target x86, or x64. My only option is ‘Any CPU’. When I access the path given, there is no game.Desktop.exe.

Any help would be appreciated.
