Project won't open anymore. Have no idea why :(

Hi guys and gals

Suddenly, for no apparent reason, UE4 just crashed on me and now every time I try to open my project, it crashes before even loading the editor. I’ve had a look at the log and it appears to be something to do with the foliage. However I have no idea how to resolve it. I’ve attached the crash log if it helps.

Please help if you can, have a huge deadline in just 4 days

Fringe, LOG FILE

Try to move your startup map to an other folder

You’re my savior! But only partly so.
The above suggestion did work, I can open the ‘project’, but trying to open the map we had been working on just crashes the editor again. I really appreciate your advice as it has partly fixed the solution, but do you have any other suggestions on how to sort out the dodgy map?

Many thanks

Wouldn’t this line suggest an issue with your cpp?

Fatal error: [File:D:\Build++UE4+Release-4.12+Compile\Sync\Engine\Source\Runtime\Foliage\Private\FoliageInstanceBase.cpp] [Line: 90]
Instance base cache - integrity verification(3): Counter: 47 Size: 43, InvSize: 42 (L:1 S:0 T:0)

Maybe something changed in the API that’s causing a crash, and that item happens to be in the map. Try opening in VS and compiling before opening in UE4.

How do you have c++ files if you aren’t a coder? Do you have someone coding the project for you? They really should be the one taking a look because this is a coding issue from what I gather.

Thank you for your suggestion, but I have to point out that I a fully fledged noob when it comes code / debugging / troubleshooting. I am basically just an ameteur 3d artist with very little technical know how.

When you say VS, do you mean Visual Studio? If so, I don’t have that software, and when you say ‘open it up’, I don’t know what to open up nor what to compile. Did you mean the Map.uasset?

On a side note, I did thankfully realise that I made a back up of the whole project around 5 days ago, so I was able to bring that in and replace the borked one and now we have the original map which is good, and won’t set us back too much. But for future reference, I would like to resolve this original issue so that I know how to fix it in the future.

Many thanks guys / gals
