I'm attempting to import XML dumps from several other Mediawiki wikis into a local install of MediaWiki running on XAMPP.

Some files import fine, but many of them get the error 'Import failed: Error creating directory shellbox-bdd810ee1edf29b3'. Number at the end changes with each attempt.

I'm running:
MediaWiki 1.37.2
PHP 7.4.27 (apache2handler)
MariaDB 10.4.22-MariaDB

I have '$wgTmpDirectory = "C:\xampp\htdocs\mediawiki_manuals\images\temp";' set in LocalSettings.php.

All of my mediawiki directories & subdirectories have full permissions. None of them are read-only. Not sure what the hang-up is.

Thanks for any help
