Error exporter BlenderToBabylonJS 6.3.0

Hi everyone,

I had updated Blender with the latest version and when I try to export the default scene (camera, cube and point light) I got an error :

How can I fix it please ?

it seems to be due to a small interface refresh problem.

Sorry for the inconvenience !

Yes some one on github posted an issue same as this. I could never reproduce, but I always restart after reloading (probably about 10k times by now). Python is not really good at getting things out of memory, so always restart Blender after upgrading an add-on.
