Export to gbXML Crashes Revit

[wyatth_tgce]

I am trying to export a gbXML file from my MEP model with a linked Architecture model using automatically-placed spaces. I use the "Use Room/Space Volumes" option and set up everything in the General Tab (Location, Ground Plane, etc.). However, when I change the "Export Category" from "Rooms" to "Spaces," the program freezes up (it starts to load, but ends up not responding even when left to sit for over an hour). I am using Revit 2019.2, which online it says that this issue was fixed. All I am trying to get is the space dimensional information for use in other software. 

Does anyone have a solution, or could this just be an issue with this particular model? 

Thanks in advance!

Hello, Would it be possible to share the models with me so that we can take a look at it? Thanks, Anna

Anna was able to help me out with this. For others who might come across this post, basically, there was just a lot of "room-bounding" geometry that wasn't necessarily bounding rooms, so Revit was working very hard to try to include all of these features in the export. Turning off room-bounding for these non-room-bounding features allows Revit to export it more easily. Thanks for the help, Anna!
