I’ve been running into several issues with using the RawInput plugin but have hashed out most of them by editing the source code. I’ve been using the ue5-main branch and just fetched the latest changes so of course this issue could be related to the fact that it’s an experimental branch.
To get more in depth on the crash, I have added some methods in to the RawInputFunctionLibrary.cpp as well as the header file that have worked perfectly fine in the editor. Here’s a slice of the cpp file with the method in question that is causing issues as well as the original GetRegisteredDevices() method:
#include "RawInputFunctionLibrary.h"
#include "RawInputSettings.h"
#if PLATFORM_WINDOWS
#include "Windows/RawInputWindows.h"
#endif
void URawInputFunctionLibrary::RefreshRawInputDevices()
{
#if PLATFORM_WINDOWS
FRawInputWindows* RawInput = static_cast<FRawInputWindows*>(static_cast<FRawInputPlugin*>(&FRawInputPlugin::Get())->GetRawInputDevice().Get());
RawInput->InitializeRawInputDevice();
#endif
}
TArray<FRegisteredDeviceInfo> URawInputFunctionLibrary::GetRegisteredDevices()
{
TArray<FRegisteredDeviceInfo> RegisteredDevices;
#if PLATFORM_WINDOWS
FRawInputWindows* RawInput = static_cast<FRawInputWindows*>(static_cast<FRawInputPlugin*>(&FRawInputPlugin::Get())->GetRawInputDevice().Get());
RegisteredDevices.Reserve(RawInput->RegisteredDeviceList.Num());
for (const TPair<int32, FRawWindowsDeviceEntry>& RegisteredDevice : RawInput->RegisteredDeviceList)
{
const FRawWindowsDeviceEntry& DeviceEntry = RegisteredDevice.Value;
if (DeviceEntry.bIsConnected)
{
RegisteredDevices.Add(RawInput->GetDeviceInfo(RegisteredDevice.Key));
}
}
#endif
return RegisteredDevices;
}
My visual studio builds the source code and project code with no errors so I assume this error might be related to some gen files being created incorrectly during the Packaging process but I’m not sure where or how I would fix it. The error log:

If anyone has any ideas or needs more information in order to help me out here then I will do whatever I can. Been stuck on packaging issues for the past week and have managed fix them somewhat such as JSBSim plugin issues and other various things so I’m just about at my breaking point.
