Thanks for the reply, I was following below doc and select table is working, issue is with create table.

spark.sql(f"create table if not exists {catalog}.{databasename}.testTable(id INTEGER, name VARCHAR(10), age INTEGER)").show()

Same issue is listed in https://github.com/unitycatalog/unitycatalog/issues/560  but not sure what exactly is the SAFE enabling.
