You need to work with your Oracle Database Administrator to capture an Oracle Trace when you try to delete the Featureclass. This will show more details, the Oracle Trace captures all SQL Statements been executed and any errors as well, you also need to capture the SDE intercept.
How To: Set up an SDEINTERCEPT Log File on a Client Machine for ArcGIS Desktop and ArcGIS (esri.com)
This will help Esri Technical Support to identify the problem.
"DisableArchiving: ERROR 003644: Underlying DBMS error [ORA-00904: "GDB_TO_DATE": invalid identifier]"
ORA-00904: "GDB_TO_DATE"
ORA-00904 - Database Error Messages (oracle.com)
"The identifier or column name entered was invalid."
You can use Oracle SQL Developer to check the fields in the Featureclass base table, A table ( if registered as traditional versioning), the Archiving Table and the Multi-versioned View (_EVW View).
It is complaining about the GDB_TO_DATE field, then check the archiving fields.
Log in as the SDE user in Oracle SQL Developer, run the following query to get a list of columns recorded in the system table.
SELECT * FROM COLUMN_REGISTRY WHERE TABLE_NAME = '<feature_class_name>';
Compare the list with the fields shown in the feature class properties dialog box in ArcGIS Pro and with the list of fields shown by Oracle SQL Developer when describe the featureclass base table columns.
