The problem is with the project itself  
There was a problem with the electrical current and the whole system shut down  
When I turned on the computer and then ran the project, it didn’t work  
but ue4 running and work fine

Ok, just checking.

Then it’s corrupted.

Do you have a backup?

Every person should back up the project if his project is large and has been working on it for a long time  
Unfortunately, I did not back up the files

Try this: make a new project and then move the Content file from the old project to the new one.

Maybe this will fix your problem.

Hi all,

I did a quick google for “Assertion failed: NumBytes == Strings.Num() [File:D:/Build/++UE4/Sync/Engine/Source/Runtime/Core/Private/UObject/UnrealNames.cpp] [Line: 3336]” and came across [this thread](https://forums.unrealengine.com/t/assertion-failed-numbytes-strings-num/489904).

Advice is to delete C:\Users\username\AppData\Local\UnrealEngine\5.0\Intermediate  
(You can also delete saved/intermediate folders in your projects and they will be regenerated on project launch)

Hope that helps!
