Crash on project open/new project

Development Getting Started & Setup

1

The editor won’t even open. It starts to load my project, and after it finishes compiling shaders, it crashes every time. No idea what to do! I’m using 5.4.4, and this is my first time using Unreal, and I’m a student with very little experience with game development in general so I’m just super out of my field here. Please help!

This is the message it gives me after crashing:

Assertion failed: uint32(Allocation.BaseIndex + Allocation.Size) <= StructMetaData.GetSize() [File:D:\build++UE5\Sync\Engine\Source\Runtime\RenderCore\Private\ShaderParameterStruct.cpp] [Line: 276]

Hello there @User_Gwen!

Welcome to game development, don’t worry, we all start with crashes and logs :grinning_face_with_smiling_eyes:

This error in particular has popped up in other threads, with a variey of solutions:

  • Please make sure your OS is updated to the latest version, and refresh your nVIDIA drivers. Pick the “Clean Installation” option, as well as going for the “Developer” drivers, as these have more stable settings for engine work

  • Since you are working on UE5.4, test switching between DX11 and DX12

  • If you recently updated UE, try deleting all files from directory C:\Users\UserName\AppData\Local\UnrealEngine (make a backup just in case)

  • If the issue affects a particular project only, test deleting the intermediate, config, and saved folders, then reopen the project (also make backup for this test)
