I/O operation on closed file when opening a file twice

[raffaeler]

I have to open a xlsx file twice in order to get both the cell values and the formulas definitions:

wb_data = openpyxl.load_workbook(xlsx_file, keep_vba=True, data_only=True)
wb_form = openpyxl.load_workbook(xlsx_file, keep_vba=True, data_only=False)

wb_data.close()
wb_form.close()

The above code produces the following exception:

Exception ignored in: <function ZipFile.__del__ at 0x00000284EDD7E480>
Traceback (most recent call last):
  File "C:\Users\XXXX\AppData\Local\Programs\Python\Python313\Lib\zipfile\__init__.py", line 1975, in __del__
