Website visitors are unable to download files

Wordpress: version: 6.4.3
PHP Version: 8.3
Download Manager Plugin Version: Version 3.2.86
Problem: When visitors attempt to download a file when “Lock options -> Enable Captcha Lock” is enabled they can complete the CAPTCHA successfully but aren’t presented with a download button afterwards. However, if an admin is logged into the WordPress site and attempts to download the same download link captcha is successful and files can be downloaded.
If I disable the Enable Captcha Lock option visitors can download the files. Any help would be much appreciated as this is something that has just recently surfaced in the last month.

I have resolved my own problem which I brought on myself in the name of securitay. My problem was I am using XML-RPC plugin 2.1.5 and I disabled the wordpress JSON REST API for not logged in users. This prevented the downloads for visitors after the CAPTCHA was complete. Sorry to be a burden.
