Tilde(~) in Path Breaks CI4 (used in iCloud Drive Path)

The issue is caused by the sanitizeFilename method on line 301 of the file vendor/codeigniter4/framework/system/Autoloader/Autoloader.php. The function transforms a path such as /com~apple~CloudDocs/sites, which is perfectly legitimate on a Mac, into /comappleCloudDocs/sites, rendering all paths invalid.

I solved the issue by changing line 307:

PHP Code:

$filename = preg_replace('/[^0-9\p{L}\s\/\-\_\.\:\\\\]/u', '', $filename); 


To

PHP Code:

$filename = preg_replace('/[^0-9\p{L}\s\/\-\_\.\:\\\\~]/u', '', $filename); 


I don't know if there is a better way to avoid making changes to system files, but with this modification, CI4 works from iCloud directory on Mac.
