New install. Crashes loading old project @ 93%. What do?

Development Programming & Scripting
1

We had a brownout over the weekend and for whatever reason my machine was hooked directly into the mains, not the UPS. Toasted C:. Machine otherwise fine. Replaced C, did a reinstall of everything and my old project won’t launch – crashing at 93% every time.

At this point I am way way way in over my head and I don’t even know where to begin, what it wants or where to start and google isn’t being much help either.

I don’t know what to do.

Any ideas?

Here is the crash report:

Thank-you for your time.

I had a similar issue lately.
In my case was a function used in a macro library that was deleted but still referenced from some UserWidget blueprints.
You can check if this is your case too by taking a look at the logs of your project.
If you have something like this before the crash:

Error: [Compiler WB_Photocamera] Macro node  Macro instance  is pointing at an invalid macro graph.
Error: [Compiler WB_Photocamera] In use pin  bIsCurrentInputGamepad  no longer exists on node  Macro instance . Please refresh node or break links to remove pin.

Then it’s definitively the same case.

I had the same problem and the same solution.
