We upgraded from 5.4.4 to 5.6.1 and we can no longer build an installed engine. We trigger it like this.

> Source/Engine/Build/BatchFiles/RunUAT.bat BuildGraph -target=“Make Installed Build Win64” -script=“Engine/Build/InstalledEngineBuild.xml” -set:HostPlatformOnly=false -set:WithWin64=true -set:WithMac=false -set:WithMacArm64=false -set:WithAndroid=false -set:WithIOS=false -set:WithTVOS=false -set:WithLinux=false -set:WithLinuxArm64=false -set:WithHoloLens=false -set:WithWinGDK=false -set:WithGDK=false -set:WithXB1=false -set:WithXboxOneGDK=false -set:WithXSX=true -set:WithPS5=true -set:WithDDC=true -set:HostPlatformDDCOnly=false -set:SignExecutables=false -set:EmbedSrcSrvInfo=false -set:WithFullDebugInfo=false -set:AllowParallelExecutor=false -set:GameConfigurations=“DebugGame;Development;Test;Shipping”

It ends up attempting to build windows shaders as PS5 shaders and it fails. This is when building installed DDC for TP\_MotionDesignBP.uproject.

Is there anyone else who ran into this and solved it?
