Hey, after i updated my windows last night, i started my pc again today to open my UE4 project, but now it keeps crashing on launch, and i’m getting this report:

Assertion failed: NumBytes == Strings.Num() [File:D:/Build/++UE4/Sync/Engine/Source/Runtime/Core/Private/UObject/UnrealNames.cpp] [Line: 3336]

Hey @des1stou1! Welcome to the Forums!

It’s a bit hard to tell what is going wrong with what you currently have provided. Could you open your install options and add “Editor Symbols for Debugging”? This should provide more insight into where your problem is. Afterward, open your project and copy the new error log when it crashes.
