Unreal Engine 5 source not working correctly

I’m using the Early Alpha Unreal Engine 5 branch and I’m getting this error here:
Building UnrealBuildTool in E:/UnrealEngine-ue5-early…
Running: C:\Windows\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe /nologo /verbosity:quiet “E:/UnrealEngine-ue5-early/Engine/Source/Programs/UnrealBuildTool/UnrealBuildTool.csproj” /property:Configuration=Development /property:Platform=AnyCPU
Missing E:/UnrealEngine-ue5-early/Engine/Binaries/DotNET/UnrealBuildTool.exe after build

That’s the error I get while trying to switch the engine version.

And as well I got an error saying that my game doesn’t have something installed error from that: Screenshot by Lightshot
