Running XR Xporter

I have been using the XR Xporter add-in with SW 2018 for a month or so.  I have just installed SW2019Beta2 and installed the new XR Xporter.

When I try to save use the file save as option for GLTF, it acts like it is working but then all of a sudden my Solidworks program closes with no errors.  Anyone else having this problem?
