The longer error message is LogCore: Error: appError called: Assertion failed: ExternalPooledBuffer.IsValid() [File:./Runtime/RenderCore/Private/RenderGraphBuilder.cpp] [Line: 1096]
Attempted to register NULL external buffer.
My laptop is running Ubuntu Linux 24.04, but I am running Unreal in a Docker container based on 22.04.
Hi! Did you resolve it? I also came across this issue!
same crash here, did you find a way to resolve it ?
I found a way to start my project again, first delete
“DerivedDataCache” “Intermediate” and “saved” folders, and try again.
If it still doesn’t work, try to open your project using cmd command and with that way, open a other map that the one you had be default that could bring the crash:
C:\epic\UE_5.6\Engine\Binaries\Win64\UnrealEditor.exe" "C:\CoolProject\CoolProject.uproject" -edit -map=/Game/Maps/Intro/Level01
cheers!
