UE4 packages, but UE5 is "unable to start communication"

I used VS 2017 with UE 4 and I’m able to package shipping builds no issue.

UE 5 initially claimed it couldn’t even find Visual Studio, so I installed VS 2019 instead.

Now, I’m still able to package UE 4 projects, but UE 5 changed it’s tune to say the following before throwing “cook failed”:

LogDirectLinkNet: Error: Endpoint 'UE5-Editor': Unable to start communication (error code:2)

EDIT: Here’s a variation when I chose to just cook stuff instead…

UATHelper: Cooking (Windows): LogDirectLinkNet: Error: Endpoint 'UE5-Editor': Unable to start communication (error code:2):
PackagingResults: Error: Endpoint 'UE5-Editor': Unable to start communication (error code:2):

Apparently, this is Datasmith’s fault. You need to enable the runtime even though you’re not using it.

I wasn’t sure what was meant by this.

To clarify I enabled the Datasmith Runtime Plugin and that solved my issue.
