Does anybody face it or guide me how to fix it?

Thank you.

Your ./sites/common_site_config.json may be malformed?

Don’t know if it is related - but many v12 users are using python3.6 - did you follow the instructions for python3? Also ensure that you have installed all the python3-devtools and other requirements as specified in the guide.
