Empty Output generated from Union operation

I am attemption to Union two shapefiles. I made sure both shapefiles have the same defined coordinates before trying to Union and I am still getting  and empty output generated warning. I found on google that some people had the same issue and after repairing Geometry it worked for them. That did not work out for me.

Does anyone have any potential solutions on how I can achieve this Union operation successfully or have any insight on why this operation completes but generates an empty output.

My task:

I have two large shapefiles that I was trying to intersect. I was limited by my computational constraints, so I gave it the classic attempt of divide and conquer. I split shapefile 1 into two shapefiles 1a and 1b. Intersected them with Shapefile 2. Now I am trying to Union the two intersects together.

Thanks in advance for any suggestions.
