Pyside6 and pywin32 cannot be imported simultaneously

Question

As a beginner in PySide6, I'm currently developing an application where I use the pywin32 package to read doc files. However, when I import both win32com.client and packages related to PySide6, I encounter the following error. enter image description here

PS C:\Users\xiaowu\VSCodeProjects> & C:/Users/xiaowu/anaconda3/envs/pyside6/python.exe c:/Users/xiaowu/VSCodeProjects/Draft/Demo1.py
Traceback (most recent call last):
  File "C:\Users\xiaowu\anaconda3\envs\pyside6\lib\tokenize.py", line 330, in find_cookie
    line_string = line.decode('utf-8')
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x90 in position 2: invalid start byte

During handling of the above exception, another exception occurred:

SyntaxError: invalid or missing encoding declaration for 'C:\\Users\\xiaowu\\anaconda3\\envs\\pyside6\\lib\\site-packages\\pywin32_system32\\pywintypes39.dll'

If someone could help me with this, I would be extremely grateful. Thank you very much！

I removed all other packages and kept only the ones related to PySide6 and pywin32, but the program still throws errors. This convinces me that there is a conflict between these two packages. I've searched online and tried changing the encoding to UTF-8, but the error persists.
