I got a bunch of Missing Engine Content errors in Output Log after starting Unreal Engine 5.7.1 …

Failed to read file ‘../../../Engine/Platforms/VisionOS/Content/Editor/Slate/Launcher/Platform_VisionOS_24x.png’ error

LogStreaming: Warning: Failed to read file ‘../../../Engine/Plugins/Animation/EaseCurveTool/Resources/Common/ButtonHoverHint.png’ error.

LogStreaming: Warning: Failed to read file ‘../../../Engine/Plugins/MetaHuman/MetaHumanSDK/Content/Intro_1.png’ error.

LogStreaming: Warning: Failed to read file ‘../../../Engine/Content/Slate/Common/ButtonHoverHint.png’ error.

… and so i was looking in the listed folders and all these folders and files are still missing after an clean install …

there was no VisionOS/Content folder,
there was no EaseCurveTool/Resources/Common folder,
there was no Intro_1.png and ButtonHoverHint.png

… and so on …

Also getting two times the error :

LogSlateStyle: Warning: Unable to find Slate Widget Style ‘ltc1q6tll6caghhc0f625wt7gkjxjmpt457lfjrpkmj’. Using FButtonStyle defaults instead.

and at least one time the error :

LogTextureGraph: Warning: serialize Var v-1<0x00000000>: NOT FOUND for None

and two times in red the error :

LogAutomationTest: Error: Condition failed

So my first question is where can i get these missing content for UE5.7.1 to fix this missing files issue - likely over an simple download of an zip-archive with all the missing content - or is there an other workaround - like disabling VisionOS support for those who do not use these

At the very least, I don’t understand why they don’t just continue to provide this as a simple download with the delivered content.

I mean, it should have been obvious that these errors would occur if the content is simply missing but is still queried by the engine at startup.

Best regards, Marc
