Hello, I am trying to compile this plugin for use in UE 5.4 and I keep getting this error when building through windows powershell:

_[9/19] Compile [x64] MqttUtilitiesBPL.cpp (0:05.26 at +0:00)
C:\Users\20036153\Documents\GitHub\UnrealEngine\Engine\Source\Runtime\CoreUObject\Public\UObject\ScriptInterface.h(27) : error C4702: unreachable code
inlined at C:\Users\20036153\Documents\GitHub\UnrealEngine\Engine\Source\Runtime\CoreUObject\Public\UObject\ScriptInterface.h(151)
inlined at C:\Users\20036153\Documents\GitHub\UnrealEngine\Downloads\HostProject\Plugins\MqttUtilities\Source\MqttUtilities\Private\MqttUtilitiesBPL.cpp(40) <call to TScriptInterface::TScriptInterface>
while compiling UMqttUtilitiesBPL::CreateMqttClient

Error executing C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.38.33130\bin\Hostx64\x64\cl.exe (tool returned code: 2)_

For what it's worth, this is my first time having to build a plugin externally since it did not work after following the steps provided(Though it did work with UE 5.2, 5.0 and 4.27 for me). Any suggestions on how to resolve this?

For the time being I have migrated back to UE 5.3 and everything works well, though I still am not sure what's going on for 5.4
