Comment (by jef):

 Quick workaround: create an empty directory .libs in
 {{{%OSGEO4W_ROOT%\apps\Python37\lib\site-packages\fiona}}} and
 {{{%OSGEO4W_ROOT%\apps\Python37\lib\site-packages\rasterio}}} or change
 {{{%OSGEO4W_ROOT%/apps/qgis/python/qgis/utils.py}}} by adding {{{and
 os.path.isdir(p)}}}:
