Page Builder with TinyMCE Widget

I’ve been having issues creating posts and pages with Page Builder. Specifically, when creating a new page, with any type of widget (i.e. single row/column with Text widget), the contents will not save. The structure will, however.

I’ve determined the issue is with Black Studio TinyMCE Widget. When this plug-in is deactivated, I’m able to save and update content. I’ve uninstalled and re-installed Page Builder as well as Black Studio to no avail. Should I try to reach out to Black Studio about this issue?

I am also using the SiteOrigin Widgets Bundle.
