Issue Exporting Medium-to-Large Assets Under 100 MB W/ No Notified Issue (Adobe XD)

I create vector graphics that are highly detailed and apply XD's 3D transform feature to add dimension.

I always struggle with the z-axis, as it often goes into the negative range when creating these large graphics. And most of the time zeroing the z-axis resuts in a totally scewed asset that changes the x- and y-axis more. So then it takes several minutes to maybe even hours to correct the zeroed assets, and at that point possibly recreating the graphic from scratch would save time instead of trying to fix the transform.

I love Adobe XD and believe it gives you the freedom to easily create and conceptualize almost anything. However, I have spent hours now contacting Adobe XD support about individual cases. I have probably contacted Adobe XD for up to 3 hours attempting to solve a problem which usually seems highly advanced for staff as they have to transfer me multiple times and sometimes never reach a conclusion after troublshooting.

In regards to this project, I spent about 20 minutes on a virtual support session where I shared my screen and gave full remote access to my computer. While this is not the representative's problem at all, he could not figure out how to export the artboard at full resolution, only 0.5x, which I cannot use. I did not have time to wait to be transferred today and after being transferred several times prior, I did not want to risk wasting time or giving remote access possibly 10 times.

Is there a better software I should use for vectorizing 3D and realistic graphic illustrations? 

I attached the notification that appears while attempting to asset the artboard I am referencing.
