SQL & PL/SQL

I'm trying to create a  script that generates sequences for each table in my data base.

But it keeps givving me this error:

ORA-00922: missing or invalid option

The code:

DECLARE
V_OWNER_NAME   VARCHAR2(100) := 'HAZARDV2';
V_TABLE_NAME VARCHAR2(500) ;
V_PK_COLUMN  VARCHAR2(500) ;
V_MAX_ID     NUMBER ;
  CURSOR ALL_TABLES IS
    SELECT table_name
            FROM all_tables 
            WHERE OWNER = V_OWNER_NAME
            ORDER BY TABLE_NAME ;
BEGIN
  FOR I IN ALL_TABLES LOOP
  
  --STORING THE TABLE NAME RETURNED FROM CURSOR
  V_TABLE_NAME := I.TABLE_NAME; 
  
  IF V_TABLE_NAME LIKE 'PS_TXN' THEN 
NULL;
ELSE
-- GETTING THE PK COLUMN NAME   
SELECT 'SEQ_'||NVL(column_name,999) 
INTO V_PK_COLUMN
FROM all_cons_columns 
WHERE
OWNER = V_OWNER_NAME AND
constraint_name = (
  SELECT constraint_name FROM user_constraints 
  WHERE TABLE_NAME = V_TABLE_NAME AND
  CONSTRAINT_TYPE = 'P'
);
  
----- THIS IS THE LINE THAT THE ERROR POINTS TO -------
   
  execute immediate
  
  'CREATE OR REPLACE SEQUENCE ' || V_PK_COLUMN || ' 
START WITH (SELECT NVL(MAX('||V_PK_COLUMN||'),0)+1 FROM '||V_TABLE_NAME||') 
INCREMENT BY 1 
MAXVALUE 9999999999999999999999999999 
MINVALUE 1 
NOCACHE 
ORDER';
   
  END IF;
  END LOOP;
    
END;

Thank you for your time.
