New XAmpp copy old WordPress files

I installed XAmpp locally with WordPress. I have installed new XAmpp on the same disk (previous XAMPP removed) and then copied all WP folders from old installation in New XAmpp at the same location.

Everything remained the same, mysql, phpmyadmin, old wordpress tabels (which I copied) in phpmyadmin all work.

But when I try to open HTTP: // Localhost/XAMPP/WP/WP-Admin/(my old WP-URL), I just get error 500 without other information (nothing in mysql-funer logbook, I have enabled all error to the detail). Nothing in WP content/Debug.log

I would like to run WordPress from earlier.

I have this message in Apache -Froutlogboek:

I have just copied all WordPress files from old installation (including HTACKES)

My HTACCESS in WP directory looks like this (I have not changed before):

# BEGIN WordPress

# dynamically generated, and should only be modified via WordPress filters.
# Any changes to the directives between these markers will be overwritten.
