When I went to compile my C++ code, the Unreal editor crashed. Since then, every time I open the project, the editor crashes with the following error:

Unknown exception - code 00000001 (first/second chance not available)

Hi!

I noticed in this line

UE4Editor_Stealth!AMainCharacter::AMainCharacter() [c:\users\mr\documents\unreal projects\stealth\source\stealth\maincharacter.cpp:15] UE4Editor_CoreUObject!UClass::CreateDefaultObject() [d:\buildfarm\buildmachine_++depot+ue4-

is that your custom Module? Has the class layout of AMainCharacter changed since you saved your content in the editor?

Is the UnrealEngine loading an old version of your game’s plugin?

If you do a clean rebuild of your plugin (deleted the compiled version, compile a new version) does this still happen?

Oh! I meant to type ACharacter. That fixed it. Thanks :smiley:
