我有一个tkinter应用程序，首先有一个login/signin页面（signin将一个新用户插入到数据库中，并正常工作），还有一个主页面，其中有一个包含元素的表和一个按钮，用于使用此函数删除元素：

def delete(self):
    with sqlite3.connect(env['DB']) as conn:
        selected = self.AuthTable.Table.item(self.AuthTable.Table.selection()[0])
        curr = conn.cursor()
        curr.execute("DELETE FROM 'Authentifiants' WHERE authId=?", (selected['tags'][0],))
        conn.commit()
            
    self.AuthTable.search()

但它不起作用，并引发：

Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Program Files\WindowsApps\PythonSoftwareFoundation.Python.3.10_3.10.2288.0_x64__qbz5n2kfra8p0\lib\tkinter\__init__.py", line 1921, in __call__    
    return self.func(*args)

  File "f:\Acces Rapide\Desktop\Tech\d3v\WorkSpace\Projects\SecurityTemp\src\app\authentifiants.py", line 104, in delete
    conn.commit()
sqlite3.OperationalError: database is locked

我认为这是因为我没有关闭conn，所以我将它们更改为with语句，但情况相同
