Assertion Failed - Nullpointer

Hi,
I am updating my project from 4.10 to 4.12. I am using the VLC plugin for my project and am building the engine from source - 4.12.5. I can open the project in the editor, but crash when I try to open certain assets or levels. I do not get the crash reporter. My error is as follows:

Assertion failed: InRawPtrProxy.Object !=nullptr
[File:C:\Users\Todd\Downloads\UnrealEngine-4.12.5\Engine\Source\Runtime\Core\Public\Templates\SharedPointer.h][Line:199]

Here are my logs and MiniDump

Hello todernst,

I’m assuming you have since you explicitly mentioned it, but have you tried disabling the VLC plugin to see if the crash is being caused by it? Also, does this happen with fresh projects created in 4.12.5 or only with this converted project?

I created this project fresh in order to compile the plugins, then I migrated the content over from the 4.10 project. I’ll try doing a standard conversion tonight to see if that eliminates the problem.

Thank you!

I was able to convert the project to 4.12 successfully. The error was introduced when trying to migrate only relevant assets to a new blank project to reduce overall project size.
