Not an answer - just some feedback after trying to reproduce the issue.
Opened the OSM using SketchUp. No initial issues. Applied "Intersect in Entire Model" from "Surface Matching":
No unusual feedback. Saved the model, and reopened:
Now getting some feedback on specific issues. Opened using the OpenStudio Application, activating "Geometry Diagnostics" and enabling "Potential Adjacency Issues":
Also pinpointing specific issues. I can't reproduce what you're describing, but I'm hoping the feedback here is enough for you to narrow down (and fix) these specific issues.

Not an answer Based on your follow-up video, I've re-hauled my previous pics and comments. The following is more focused on the specific areas you've highlighted.
Zoom in the problem area (before intersecting the entire model). I used SketchUp's tape measure to highlight the tiny azimuth difference between Surface 253 and Surface 343. I think this is the source of your issue. I think this pushes OpenStudio to recognize the vertex (joining both wall surfaces with the floor above) as being collinear - just some feedback after trying to reproduce the issue.
Opened the OSM not good. Just like any tiny overlap between 2 surfaces, OpenStudio users should really try to avoid slight azimuth differences between connected surfaces. Both wall surfaces are outdoor-facing walls - you should be able to fix this using SketchUp. No initial issues. Applied "Intersect in Entire Model" from "Surface Matching":
No unusual feedback. Saved the model, and reopened:
Now getting some feedback on specific issues. Opened using the OpenStudio ApplicationSketchUp.
Once intersected, activating "Geometry Diagnostics" and enabling "Potential Adjacency Issues":
Also pinpointing specific issues. I can't I'm able to reproduce what you're describing, but I'm hoping the feedback you've shown in your video (i.e. tiny gap between newly-generated floor surfaces):
However, if I save the newly intersected model, then reopen using SketchUp:
The tiny gap between floor surfaces has been auto-corrected, assimilated with a larger surface. Yet this inadvertently ends up creating a cutout, which OpenStudio corrects by converting it to a (transparent) sub surface, illustrated here is enough for using the OpenStudio Application.
The intersected model would obviously need fixing. I strongly suggest you to narrow down (and fix) these specific issues.fix the initial issue, rather than try fixing an intersected model. My 2-cents.
