Hello @matin73 , sorry for the late response.

Can you say if this issue is still relevant? In TYPO3 12, the section around /typo3/sysext/core/Classes/Resource/Driver/AbstractHierarchicalFilesystemDriver.php line 53 has been changed, which makes me wonder if the problem still exists or not.

Can you confirm?

@matin73 please try the latest version of the extension, I would close the issue, if the problem still exists please open the issue again.
