The "All Software" tab relies on an aggregated table built by a specific cron job script named cron_all_software.php. If this script hasn't run or failed, the aggregated data won't be available for display. You can manually run this script to rebuild the data:
/bin/php /usr/share/ocsinventory-reports/ocsreports/crontab/cron_all_software.php
PHP or server incompatibilities: Recent OCS versions require PHP 8.0 or higher. Using older PHP versions can cause parts of the web interface to malfunction, including showing empty software lists.

OiD mentioned "Somehow there was a missing table named 'software_link', manually adding it and running cron_all_software.php solved it."
