Issue building Nakama for unreal 5

Hi, I am trying to setup Nakama in unreal but I am having some issues!

I have followed the steps and add the latest version into the Plugins folder. I then go into the plugins tab and select Nakama from the list. After the restart it says it needs to recompile NakamaBlueprints, NakamaCore and NakamaUnreal but it fails to compile.

The erros says to try rebuilding from source so I have tried rebuilding the solution and get these errors:, 40): [CS0103] The name ‘UnrealArch’ does not exist in the current context

Could anyone help me out with what the issue might be?
