EpicGamesLauncher side bug

This issue is caused by some wet bug on UnrealEngine/EpicGamesLauncher side:
While DirectX Build.cs file is present on GitHub in 5.2 branch（ https://github.com/EpicGames/UnrealEngine/blob/5.2/Engine/Source/ThirdParty/Windows/DirectX/DirectX.Build.cs ）, it is missing in Unreal Engine 5.2 installation from Epic Games Launcher And other Build.cs files are actually using methods from this DirectX class That's why Rider and ReSharper C++ Highlight them as errors
Hopefully this issue will be addressed by Epic Games in the bugfix.

As a workaround you may download this file from the official repository (by the link above) and place it in your Unreal Engine installation folder, for instance: C: Program Files Epic Games UE_ 5.2 Engine Source ThirdParty Windows DirectX After regenerating project files the issue will disappear.
