I am habing trouble with xlwings and win32com.client, both xlwings and win32com.client have been working fine up until recently. 
When i try to import xlwings for example.
import xlwings
I get an ERROR below:
_pickle.UnpicklingError: invalid load key, '\x00'
I get a similar error when i run the code below:
import win32com.client, 
but get no error when i run 
import win32com
i have tried uninstalling python and reinstalling it again but the issue still persist and reloading the modules.
I resolved this issue uninstalling xlwings, erasing the content of this folder
C:\Users\YOUR_USERNAME\AppData\Local\Temp\gen_py\3.8
and then reinstalling xlwings.
(Anaconda 3 Python 3.8).
