ETL Job fails with ORA-00166 after patching

After patching an Exadata machine with RU 19.22.0.0.0 from 19.19.0.0.0. However, after patch was applied Data Loading jobs now fail/terminate with remote/local nesting level is too deep error. The job runs for about an hour loading some tables before failing, even after a manual re-run. There's no current workaround. 
The data load (ETL) job creates dynamic sql (merge commands) to insert/update existing table over a dblink (remote DB), then runs each sql (one per table).

DBaaS Exadata
Oracle Lunix: 8.9

Need help to determine what has changed with the latest patch set. As these jobs have always worked through previous patching cycles. Could this be parallelism related?
