Why won't parallel pool start under MCR r2022b?

I have a codebase that starts a local parallel pool when performing one unique operation. I'm running this code inside a Windows Server 2022 environment. This codebase successfully launches the local parallel pool, and the pool performs all operations successfully, if I execute the code from within Matlab r2022b via the Command Window. But if I compile it into an application and launch the executable, the executable is unable to start the local parallel pool successfully. The executable is able to perform all other operations successfully; just not the operation starting the parallel pool. Any thoughts about why the executable does not function correctly?

I have the same problem. I export the cluster profile of 'Local' into local.mlsettings and pass it to the executable file as an input argument. But the parpool function crashes:

Starting parallel pool (parpool) using the 'local' profile ...

Error using parpool (line 149)

Parallel pool failed to start with the following error.

Error in tmpVelVorMean_LSC_Ver9_Curta (line 125)

Caused by:

Can you confirm that you've included the cluster profile in your application? See this documentation page for more information.

Yes. I've exported the cluster profile as a .mlsettings file and it is included in the application package.
