C++ 4.19 Transition Guide

[anonymous_user_c2113cad]

Hi, I’m trying to update from 4.17 to 4.19.

Unfortunately, Unreal crashes when starting or during shader compiling

I get this error message:

Error: Fatal error: [File:D:\Build++UE4+Release-4.19+Compile\Sync\Engine\Source\Runtime\ShaderCore\Private\ShaderParameters.cpp] [Line: 24]
Error: Failure to bind non-optional shader parameter SplineStartOffset! The parameter is either not present in the shader, or the shader compiler optimized it out.

Has someone a Idea how to fix this?
I’m a little lost right now
