#### Code Sample, a copy-pastable example

```python
[NXTS122ND8S10.xlsx](https://github.com/pandas-dev/pandas/files/6165254/NXTS122ND8S10.xlsx)

I have this trouble that pandas cannot open any xlsx files. All of the xlsx files can be open and read by excel.

Current packages and versions in use:
pandas: v1.2.3
openpyxl: v 3.0.7
python : v 3.8.5

method 1:
excel = pd.read_excel('NXTS122ND8S10.xlsx',sheet_name='Run results',engine='openpyxl')
print(excel)

method 2:
excel = pd.read_excel(open('NXTS122ND8S10.xlsx','rb'), sheet_name ='Run results')
print(excel)

method 3:
wb = openpyxl.load_workbook('NXTS122ND8S10.xlsx')
sheet = wb.worksheets[0]
excel = pd.dataframe(sheet.values)
print(excel)

method 4:  
excel = pd.read_excel('NXTS122ND8S10.xlsx')
print(excel)

same error code:

Traceback (most recent call last):
File "C:\Users\XXXXX\AppData\Local\Programs\Python\Python38-32\lib\site-packages\openpyxl\descriptors\base.py", line 55, in _convert
value = expected_type(value)
TypeError: Fill() takes no arguments

During handling of the above exception, another exception occurred:
