WordPress Member Directory Fix

I need help resolving an issue with a WordPress website where the member directory is stuck in a loading loop and never finishes loading. The site uses Ultimate Member for membership management and directory display. Recent system patches may have caused the problem, and I need someone to diagnose the issue, identify the root cause, and implement a fix so the directory loads properly again. Experience troubleshooting WordPress performance and plugin-related issues is important. The membership application form is currently not linked to the user list or Ultimate Member. So I have to manually transcribe the application details into the user list. I would like improve the membership application process to automatically update the user list. When the application is approved, the new user is then automatically made active
