Missing global shader FLGUIResolveShader8xPS's permutation 0, Please make sure cooking was successful.

Hi! I’m getting this error when I try to cook my packages on both UE5.4 & 5.5, and I don’t know how to solve it.

Hi there. I upgraded my project from UE 5.3.2 to UE 5.4.2. Packaging is going fine with only 1 error - UATHelper: Packaging (Windows): /Engine/Generated/Material.ush:3338:5: error: use of undeclared identifier ‘View_TemporalAAParams’ Trying to open the packaged game throws this - Missing global shader FUpsampleCS’s permutation 0. Any ideea please?

Thanks for replying. The error isn’t exactly the same but may also come from a plugin; I just don’t know which one. I found that thread and tried to follow the steps anyway, but it didn’t solve the issue. As the other thread the error comes when I try to launch the game.
