Why does UE 5.0 work but UE 5.4 crash on startup?

Hey @NanoPixel

does this happen

• When you try to start the engine itself (UnrealProjectLauncher where you can select project presets etc.)
• When you try to open an old project from another UE version?
• When you try to open a blank project?

Unreal engine 5.4 crash on start up or even open any project

Every attempt to create a new project or open an existing project from version 5.1.1 results in a crash during shader compilation.

Here are the troubleshooting steps I have already…
