Steam Workshop not Loading

[Talcove]

I start ModBuddy, I go to the Steam Workship tab and I press 'Begin.' I see the loading circle for, maybe, a second, but then I get a popup saying that ModBuddy has stopped working. Sometimes I don't get this popup and the loading circle just spins infinitely. It still lets me upload my stuff, but it never actually appears in my workshop, even if it says it worked.

Is anyone else getting this problem?
How do I fix this?
