PHP Class not found when already loaded - php

Question

Somehow this part of my class does not seem to work. In other methods I'm using the same Package class and it does not give an error. Can anyone tell me what I am doing wrong?
$package = Package::get('Package', $data['Package']);
This is the error log:

UPDATE:
For some reason it doesn't load the Package class properly when the upload button is clicked.

This is the code that should load the classes:
spl_autoload_register(function ($class) {
$try = [
'src/models/%s.php',
'src/controllers/%s.php',
'src/%s.php',
'framework/%s.php',
];
foreach ($try as $path) {
$s = sprintf($path, $class);
if (file_exists($s)) {
require $s;
error_log($s . " loaded!");
return;
}
}
return false;
});
ANOTHER UPDATE
I debugged some of the importers:

It is not found, while it is the right location. It is possible that it has to do with the triple slashes?
