Errors when building from source 4.26 and 4.27 chaos

Hi

I’m having trouble building ue 4.26 chaos and ue 4.27 chaos.
I’m getting these errors as in the image.

I have tried and followed this solution but it didnt work for me : https://answers.unrealengine.com/questions/1034296/building-ue-427-fails-due-to-missing-physx-headers.html

I’m building once again after using this solution : https://answers.unrealengine.com/questions/1008834/ue-426-from-source-build-fails-enginesourceruntime.html . I will update if it works for me or not.

Image is attached for the errors.
