Cannot access security dashboard

I cannot access the "Security dashboard" to change my password, two-factor authentication, or anything else on that page. I can log in fine. I can access any other part of my profile fine. But whenever I click "security dashboard" I get stuck at a blank page. Nothing. Not even an error message. I have tried a dozen times using Incognito Mode, turning off all my browser extensions, trying multiple browsers (Chrome and Firefox). Same result every time. I can log in fine, but the only page that goes to nothing is the Security Dashboard. What the heck?
