Adding SpriteFont Description causes error MSB3073 on latest MonoGame with Mac OSX High Sierra (10.13)

I’ve had this issue for a while, so I created a new project and ran the game (which it worked fine), then I added a SpriteFont description and ran the game again, I was met with the following error:

/Users/user/.nuget/packages/monogame.content.builder.task/,5): Error MSB3073: The command “dotnet “/Users/user/.nuget/packages/monogame.content.builder.task/…/tools/netcoreapp3.1/any/mgcb.dll” /quiet /@:”/Users/user/Monogame Projects/texttesting/texttesting/Content/Content.mgcb" /platform:DesktopGL /outputDir:"/Users/user/Monogame Projects/texttesting/texttesting/Content/bin/DesktopGL/Content" /intermediateDir:"/Users/user/Monogame Projects/texttesting/texttesting/Content/obj/DesktopGL/Content" /workingDir:"/Users/user/Monogame Projects/texttesting/texttesting/Content/"" exited with code 134. (MSB3073) (texttesting)

And the error when pasted in the terminal:
-bash: syntax error near unexpected token `5,5’

Any help is appreciated!
