server can't start after editing my.ini

[JIA YANG]

I tried to enable remote access to MySQL Server 8.0.14 on windows 10, using modifying bind address method, it was not successful, then I restored the my.ini to the original one, but still can't start server at workbench, then tried in windows cmd. I got the following errors. I saw a similar issue is solved by repair datadir=C...., but mine is ok, pointing to correct folder, which I never changed.
