I have a script I have been running in Windows 10 for quite some time and it has been working flawlessly. What it does is irrelevant, you can probably figure out by reading the code, but to conclude it it would be to say that it extract certain slopes in certain aspects.
After a major power out the main drive crashed and I had to reinstall Windows, I thought upgrading to Windows 11 would be a good idea. However, now that I am running the script on Windows 11 the shapefiles produced are empty. There are no errors reported.
Script:

I finally found what was wrong. It was the version that didn't support my script. I was using 3.26.2 before upgrading to Win11. Running on Win11 I have been using 3.28. Could there be some change in the GDAL which shows in the scripts? In any case, it's weird since it raises no errors.
