Valid initData to Build Channel?

I recently made a few minor updates to some code and now when I try to run it I'm receiving the following error message:

"Must have valid initData to build channel."

I didn't see much about this searching online and I'm confused what steps I could even take to resolve this? Thanks.

Do you have a minimal reproduction that you can post to demonstrate the error? Also, perhaps the answers here "Must have valid initData to build channel" might help.

It's a large sequence of code inside of a parfor loop so I'm not quite sure how I could. What's confusing is I've run nearly the same model historically without this error ever occuring however now it's taking place. Is it somehow related to memory?

Also I've noticed when I run the model there is now the following message in the Command Window which I don't recall ever seeing previously:

"Preserving jobs with IDs: 114 because they contain crash dump files.

You can use 'delete(myCluster.Jobs)' to remove all jobs created with profile Prod2018a. To create 'myCluster' use 'myCluster = parcluster('Prod2018a')'."
