I get the error data base is locked, what should I do?

Question

Python

I want to check the database, but for some reason I get an error that it is closed

def newMessage_text():
    with sq.connect("vebinar.db") as con:
        cur = con.cursor()
        newMessage = cur.execute("select message_text from admin where telegram_id = '631914657' ")
        newMessage = cur.fetchone()[0]
        prevMessage = cur.execute("select prev_message_text from admin where telegram_id = '631914657' ")
        prevMessage = cur.fetchone()
        if prevMessage != newMessage:
            print('+')
            cur.execute(f"update admin set prev_message_text = '{newMessage}' where telegram_id = '631914657' ")
        elif prevMessage == newMessage:
            print('-')
        time.sleep(5)
        newMessage_text()
newMessage_text()
