If you are still using CentOS 7.9, it's time to convert to Alma 8 with the free centos2alma tool by Plesk or Plesk Migrator. Please let us know your experiences or concerns in this thread: CentOS2Alma discussion
Usually means the files has the wrong type of permissions. If you have RDP access to the windows server, I would suggest running Plesk Reconfiguration and have it scan and correct the permissions to see if that resolves the issue.
you should check errors with the help of log - files, because with a decent log - level definition, they mostly point directly to the issue/cause/failure.
If the cause is a low limit setting for PHP, when uploading files, then you could increase post_max_size and upload_max_filesize limits at "%plesk_dir%\admin\php.ini"
