Attempting to load the Level 3 Capstone (via the “Launch Capstone Sandbox” button) results in a nondescript “‘access” error, accompanied by a generic HTTP 500 error when the browser-tools network tab is inspected during page load. Other modules (including for Level 3) work fine. Other people I’ve talked to are able to successfully load this project. How do I fix/revert whatever is wrong with my account in particular?
