Hello

Running OpenKM Version: 6.3.11 (build: d7abb25) on a Rocky Linux machine, everything is working well except when I try to export portion of the repo to a local path on the server, I get a HTTP Status 500 error (see screenshot). This occurs only while trying to export to a specific path, but as far as I can tell, not on other paths. Please note that this function was working perfectly a few months ago when I did a backup of the repo.
