The issue seems to be in this line: https://bitbucket.org/cioapps/pywapor/src/be893045f47467917dbd0774cb661bd0377b8803/pywapor/collect/protocol/cog.py#lines-90

The temp_path is not completely closed before it is opened again in Line 99

Fix: adding this to close the file completely.

  # Run gdal.Translate.
  ds_ = gdal.Translate(temp_path, url, options = options)
  ds_ = None
