python coverage error during html report (NoSource: No source for code:)

Question

I encounter the following error during reporting html coverage.

myrepo>coverage report html
html   NoSource: No source for code: 'C:\Users\usr\AppData\Local\Programs\Python\Python37-32\Lib\html': [Errno 13] Permission denied: 'C:\\Users\\usr\\AppData\\Local\\Programs\\Python\\Python37-32\\Lib\\html'
Name    Stmts   Miss  Cover
---------------------------
No data to report.

However, the directory exists, and I have permission for that:

myrepo>ls -la C:\Users\usr\AppData\Local\Programs\Python\Python37-32\Lib\html
total 172
drwxr-xr-x 1 usr 197121     0 Nov 26  2018 .
drwxr-xr-x 1 usr 197121     0 Nov 26  2018 ..
-rw-r--r-- 1 usr 197121  4888 Oct 20  2018 __init__.py
drwxr-xr-x 1 usr 197121     0 Nov 26  2018 __pycache__
-rw-r--r-- 1 usr 197121 77824 Oct 20  2018 entities.py
-rw-r--r-- 1 usr 197121 18191 Oct 20  2018 parser.py

Note, that I can print coverage report in terminal:

myrepo>coverage report
