Hi, I had the same problem and I got response from Databricks suport that:
"
There was a DBR release on 7th August (14.3.10 -> 14.3.11).
Our engineering team identified the issue and the fix is scheduled to be deployed on September 16th.
Until the fix is deployed, You can use the below custom spark image version in your cluster.
enter the below in the Custom Spark Version: The custom image provided was the old DBR prior to 8th August.
custom:release__14.3.x-snapshot-scala2.12__databricks-universe__14.3.10__9b6cd4f__debafb7__jenkins__1cbb705__format-3
