Errors during generation, not sure what's wrong

I’m getting errors on all projects during generation of the site, which in the end contains the projects, but no code.

In the first phase of the generation, each project outputs something similar to this:

10:39:25 21-11-2018 10:39:25: First chance exception

It looks like it stems from pretty much the same thing. Any ideas what might be wrong?

Output from 1.0.20 looks great, despite the few remaining error messages.

Btw, are you aware that you published it to nuget as SourceBrowser and not Microsoft.SourceBrowser like the previous versions?
