UE5 Editor doesn't automatically open Rider EAP IDE

[EzioMercer]

Hi!

The problem is described in title

I tried both “Rider” and “Rider Uproject” options

When I double click on C++ class or trying Tools → Open Rider in UE5 Editor I just see this notification in the left bottom corner:

but nothing is happen

When I switch to Visual Studio everything works fine

Here is some information about my programs:

Name	Version
Windows	10 (22H2)
Rider EAP	2024.2 EAP2 build 242.15523.27
Unreal Engine	5.4.2

Can someone please help me? I will glad to provide any additional information which you need

The answer of Rider stuff (Alexander Pirogov):

As a super hacky-hack for the time being, you can do next:

1. Copy RiderSourceCodeAccess plugin from the Engine into the Game/Plugins folder

2. Remove Binaries and Intermediate folders from a new location

3. In RiderSourceCodeAccess.cpp, swap

   FProcHandle Proc = FPlatformProcess::CreateProc(*PlatformAppAndArgs.App, *PlatformAppAndArgs.Args, true, true, false, nullptr, 0, nullptr, nullptr);
   

   with

   FPlatformProcess::PushDllDirectory(nullptr);
   FProcHandle Proc = FPlatformProcess::CreateProc(*PlatformAppAndArgs.App, *PlatformAppAndArgs.Args, true, true, false, nullptr, 0,
   												nullptr, nullptr);
   FPlatformProcess::PopDllDirectory(TEXT(""));
   

P.S. In my case the file named as RiderSourceCodeAccessor.cpp but I think it is just a typo
