I found out the issue. The problem is with this flag in Target.cs

> ```
> if (Configuration == UnrealTargetConfiguration.Shipping)
> {
> bUseChecksInShipping = true;
> }
>

I tried to create a simple ThirdPerson project, add a C++ class to get the Build and Target files. Add bUseChecksInShipping = true; and build it in shipping mode, it’s crashing with the same error as above:

> LogWindows: Error: appError called: Assertion failed: GraphicsContext [File:G:\5.1.1\Engine\Source\Runtime\RHI\Public\RHICommandList.h] [Line: 581]  
> There is no active graphics context on this command list. There may be a missing call to SwitchPipeline().

This was not happening in 4.27.2, the flag bUseChecksInShipping could be used in shipping builds without any problem.

UPDATE: I found out that’s an already logged ticket as well: [Unreal Engine Issues and Bug Tracker (UE-171275)](https://issues.unrealengine.com/issue/UE-171275)
