No output CSV generated in FebrlExample.ipynb when running trainMatch on Azure Databricks cluster

Hi, I am running Zing 0.5.0 on Azure Databricks. I am trying to run the FebrlExample.ipynb notebook. It's running on a 16.4 - Spark 3.5.2 - Scala 2.12 cluster. I am able to run through the entire program but once I run the "trainMatch" phase of the model, it processes everything for a few minutes but does NOT produce any outputs (i.e., no CSV is produced in DBFS). I have tried switching my cluster runtimes to 15.4 LTS and 14.3 LTS but neither of those work either. I also checked the driver logs of the cluster and didn't see anything related to a failed save. I've seen several people online having similar issues before regarding no output CSV being generated but I'm wondering if there are any known solutions to this?
