MonoDevelop crashes upon loading any project

Running the latest version of Manjaro KDE.

MonoDevelop will launch, but upon creating or loading a project (Console application), I get a pop-up that says "fatal error" and says it'll send crash info off to the devs. If I re-launch the program and try again, it'll just close immediately after loading the project.

I have reinstalled the program and tried rebooting the device, but the error is the same.

Searching for the problem returned one thing from 2013 but that was a crash on launch rather than loading a project, and another that said disabling a add-in would fix it, but disabling this add-in did not work.

I'm not sure what else there is to do.

Thanks for any help.
