Additional Information

There are two errors in the user's script: 1. The workspace path must not include the actual table. For example, arcpy.env.workspace = r"D:\-user-\Cases\Open_cases\02849687\US_cities.gdb" The user's script includes the table in the workspace path, which caused error 000735. 2. Using the list syntax in Python requires another set of quotes, single quotes, around the field values. For example, arcpy.CalculateFields_management(r"C:\Users\-name-\Documents\ArcGIS\Packages\U.S.Cities_a015c0\p20\us_cities.gdb\cities", "PYTHON3",[["Name", "'Test1'"], ["Office", "'z'"]]). The single quotes are missing from the script.
