Larger File Size won't open and crashes Adobe XD

I've been working in a file that has multiple boards with many Adobe Stock Illustrator vector graphics placed into XD which have meshes and blends. These files when imported default to extensively large files with 100+ layers for each level of blended %. The files have become large but were saving until today when the file crashed the program. I cannot open the file, 1.03 GB which takes a full minute to complete the bar before crashing. Here is what I've tried and failed:
1- Uninstalled XD, rebooted and installed again on iMac, OS High Sierra, 10.13.3, 32GB 1600 MHz, DDR3, 3.4 GHz Intel Core i7. 
2- Logged out and back into Adobe. 

3- Opened older versions of the file from Time Machine, still large, but not opening.

4- Made copy from backup Dropbox file, renamed before opening.

5- Failed in same way on Macbook Pro, which is macOS Catalina, 10.15.5, (updated today during troubleshooting), 2.4 GHz 8-Core Intel Core i9, 32GB 2667 MHz DDR4.
6- Logged out/back into Adobe on Macbook.

7- Tried opening multiple copies. Will only open files smaller than before. 
Also having enormous issue with SVG exports to Zeplin which they are working on. I believe it is tied to the large vector layers rendering the long shadows created by Adobe Stock illustrators in Adobe Illustrator and placed into XD. I'll open a separate ticket for this but all of this is occuring in same client files. 
Appreciate your help. After 5 hours of failed effort, I'm rebuilding the files tonight.
