Engine crashes when loading a specific map, or any autosave file from map

Ok so this is a pretty big deal as 4 months of work and a lot of money has gone into this one umap file.

I went to test out map by launching a .bat file so that I could play it as a standalone just as I’ve done with other maps and it crashed. Then I went back into engine to just use PIE again and it crashed. Opening any previous auto save of map crashes it as well. All other maps work fine. Launching from VS, project compiles with 0 errors or warning but will crash if I open that specific map still.

Is there anyway to re-build map without opening it? There must be a way to fix this. Here is error:
