Error when loading site after successful build

When using Hugo 0.153+, running hugo server with --watch=false, all my projects successfully build, but they break when loading them in the browser. In the browser I get the Hugo version and a “Reload Page” link; in the terminal I get the following message:

ERROR Failed to render "/": Build called multiple times when not in watch or server mode (typically with hugolib.Test(t, files).Build(); Build() is already called once by Test)

Note that there is no error when using Hugo 0.151 or 0.152, or when using hugo server without watch=false in 0.153+. Is there a change in 0.153 that can account for this?

Thanks!

This is easily and consistently reproducible.
