MySQL 5.7 installed via brew now getting ERROR! The server quit without updating PID file (/usr/local/var/mysql/dev_box.local.pid)

问题

I had mysql version 8 earlier, due to some dependency i had to downgrade to 5.7 so installed mysql@5.7 via brew.

Steps

brew uninstall mysql
brew install mysql@5.7
mysql.server start
brew link mysql@5.7 --force

Now once i have stopped the server and now i want to restart it but i am getting

ERROR! The server quit without updating PID file (/usr/local/var/mysql/dev_box.local.pid).

When i do

mysqld --initialize

I am getting

[ERROR] --initialize specified but the data directory has files in it. Aborting.
[ERROR] Aborting

But when i try to start the server using services it's starting but i am not getting anything in the grep but when i do "brew services list" it's showing that server is started. but i am not able to login

mysqladmin -u root password 'password'

This gives the error

mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)'
Check that mysqld is running and that the socket: '/tmp/mysql.sock' exists!

I have tried almost everything from

MySql server startup error 'The server quit without updating PID file '

After MySQL install via Brew, I get the error - The server quit without updating PID file

With no luck, hoping for some quick help.
