Hi there!
I'm trying to run the Prepare Time Lapse Polygons tool to create a bunch of service areas from my public transit-enabled network data set but I receive the following error:
Failed to get Service Area result from parallel processing.
concurrent.futures.process._RemoteTraceback:

The above exception was the direct cause of the following exception:

Service Area script failed.
Failed to execute (PrepareTimeLapsePolygons).
Based on the messages this happens right after the tool calculates the first set of service areas:
Solving Service Areas in parallel...
Finished Service Area calculation 1 of 24.
I am able to use the Calculate Accessibility Matrix and Calculate Travel Time Statistics tools without error, and the built-in Service Area tool in ArcGIS Pro also works for me. I am running ArcGIS Pro 2.6.3.
Here are the input parameters that I've used:

@MelindaMorang do you have any idea what I can do to fix this, or any other information that would be useful for you to diagnose the problem?
