Internal Server Error

When I accessed the flow welcome screen, the following message was showed.
Internal Server Error
The error log is as follows.

This is very odd, since the .htaccess provided with Neos/Flow does not contain a <Directory entry. So my question would be, what is the contents of the file C:/Apache24/htdocs/tutorial/Web/.htaccess in your case?
Did you just install (via composer?) the Flow distribution or did you manually edit the .htaccess?

Thank you for your reply.

Actually, I was editing the .htaccess file, so I restored it to the original state.
Then the error on the above two lines of Directory error, but the other ones are displayed. There are 500 errors.
