Unreal Engine Issues and Bug Tracker (UE-101079)

Description

OpenGL is supported but deprecated in 4.26
OpenGL4 is deprecated, you can comment this back in to add it to your targeted RHI list
If you comment this back out you can package for Linux without an issue.
If you add this RHI to windows and open QAGame the editor will crash with a shader callstack.

Steps to Reproduce

Open the BaseEngine.ini from 4.26 Binary
Enable +TargetedRHIs=GLSL_430 under [/Script/LinuxTargetPlatform.LinuxTargetSettings]
Open the editor and create a blank project
Package for Linux
Result: failed to build with global shaders failing to compile based on what project you are using
Expected: Able to package for Linux with OpenGL4
