you for reaching out on the community and telling us about your issue. I do
apologize for the issue you're having. I'm wondering here what's causing the issue. Were you previously able to export without an issue? One thing we can attempt here is to see if a mondo patch can help with getting the program to function properly when we try updating. It'll be a good step to take here. I'll leave steps down below.
Once you get the chance let us know if you're able to get the export working properly. If not we'll see what we can try next.
