Hi UE 5 user here, @lucoiso today installed the plugin, and not using it yet, but when packaging getting this error:
s): libpugixml-windows.lib(pugixml.obj) : MSIL .netmodule or module compiled with /GL found; restarting link with /LTCG; add /LTCG to the link command line to improve linker performance
UATHelper: Packaging (Windows): Creating library D:\UNREAL\CS\Binaries\Win64\ClimateState.lib and object D:\UNREAL\CS\Binaries\Win64\ClimateState.exp

UATHelper: Packaging (Windows): D:\UNREAL\CS\Binaries\Win64\ClimateState.exe : fatal error LNK1120: 2 unresolved externals
Also this error (low priority)
LogBlueprint: Error: ProxyFactoryClass null in K2Node_AsyncAction /Game/System/UI/UI_Main.UI_Main:EventGraph.K2Node_AsyncAction_0. Was a class deleted or saved on a non promoted build?
Notice, there was a node placed but not connected to anything. Unclear if this is new error with UE 5 or also due to some settings of your plugin. Bottom line have to remove plugin and unconnected nodes to build.
