The new error is also an Out of Memory error, typically associated with building lighting. Since you cannot open your project to fix, I suggest increasing /memory paging as describing as described in the following post:

If this is not possible, if you have access to your School’s computer, I would open the project, build/rebuild the lighting and save. Then, with permission, update UE4.10.2 to UE4.10.4 and make sure it opens in this environment. Be sure to build and save lighting. Then when you try to open your project on your home computer, if it still does not open we will at least be comparing “apples to apples.”
Finally, you have not said if you have tried installing UE4.11 preview and opening a copy in that version. Please include this information.
