Export issue

Hi, I’m trying to export my model as a .gtif/.glb, I downloaded the plugin, but I’m unable to save; it just stalls/freezes for some time until it unfreezes and I can try to press “save” again, only to have it all repeat. …and I am then unable to exit the save window. I have to force quit Sketchup. How come? Any tips?

(I’m on a MacBook Pro 2017, running Sketchup Pro).

Might want to confer with the author of the plugin.
