MySQL no longer starts.Please let me know the solution!

I'm a beginner in programming.I tried it through trial and error, but I couldn't solve it, so I have a question.

Mysql installed on xampp has stopped starting, and the database is not available and the blog I am currently running has stopped.
What we did just before the problem occurred was
①Local installation (hosts file rewrite failed during site creation)
②I tried to create a database for a new wordpress installation, but I couldn't create a user.

screen capture of mysql boot failure.

Also, the contents of mysqlllog are as follows:

It also says to look at Windows Event Viewer, so first of all...

First of all, I'd like to ask you something suspicious.

I tried to create a database for a new wordpress installation, but I couldn't create a user.

By what means?Have you installed a new MySQL?
The information of the screen capture and the log written on it (there should be other logs with WARN or ERROR output as it is only NOTE...) are all right, so are there any other logs?
元The original log says something about Port, so I'm worried.
