Customizing Plone 5.1.6: Bundle Builder hangs forever

[espenmn (Espen)]

I never found out why but I have the same problem

Bundles Building /@@resourceregistry-controlpanel in Plone 5.2

Seems like building bundles is broken (again) in Plone 5.2 For me, the building just 'keeps on forever' Probably due to a javascript error: TypeError: undefined is not an object (evaluating 't.window.requirejs.optimize') Can anyone confirm this? Can I rebuild from the command line ?
