I was trying out Openpyxl, and wrote the following code:
from openpyxl import load_workbook, __version__
workbook = load_workbook(filename="Contacts.xlsx")
sheet = workbook.active
That's it, no other code.
I got the following error on running: (TL;DR, due to line 2, I got "TypeError: __init__() got an unexpected keyword argument 'extLst'")

I've searched for similar problems and found one, but it was from 2014 so the solution given was to download version 2.0 of Openpyxl instead of 2.2. The openpyxl version is 3.0.4, python version 3.8.3, and Contacts.xlsx definitely exists in the same folder.
Edit:
Making a new file had worked, but I recently made another program using openpyxl. It was working fine but it suddenly broke, giving an error very similar to the one above (I didn't record it at the time, but the last line TypeError: __init__() got an unexpected keyword argument 'extLst' definitely matched).
I had made no changes to the program between the successful runs and the unsuccessful ones, so I concluded the file was at fault. I had opened and closed the file once, though I don't remember whether the very next run was the one when it broke. After the error appeared, when I opened the file I couldn't save any changes - it gave some sort of error.
Note: I don't have Office, so I'm using Planmaker of the SoftMaker Office Suite to open the .xlsx files when I need to.
I deleted the file and created a new one with the same name so as to not change the code, but the problems persisted with the new file, including the inability to save changes.
Only when I created a new file with a different name did the code work.
It may not even be an openpyxl problem, but rather a Planmaker problem, though I don't understand why the error would be the one I keep getting.
Neverthless, If someone could explain why this happens or how to fix it, I'll be really grateful. Meanwhile, I'll see if a file I never use openpyxl on will still give me the same problem, and if it does, whether openpyxl gives the same error with that file when used in a program.
