[bug] Can no longer sign in after deleting Cache folder contents.

[LastStopITSolutions]

So I was updating to php8.1 so I could update to the latest version of yetiforce and after installing php8.1 yetiforce still kept saying i was using an outdated php version. So i deleted the files inside the cache folder (usually what you do when something like this happens) and now no one can login to yetiforce. It says its missing the file /var/www/yfcrm/app/Session.php.

Error log below

You cannot delete the entire contents of the cache directory. The directory structure inside should be preserved.
Restore directories according to this structure (https://github.com/YetiForceCompany/YetiForceCRM/tree/developer/cache)
and verify appropriate permissions for these directories.
