SSO error blocks student access via ClassLink

Launching Pathful from the ClassLink dashboard returns a 'Whoops! Single Sign-On Error' page instead of the application, with reference code 2026-09-17_16.05.32_a97fb25aba8dc21c93d4a220064af293. The affected student (ID# 724467 - Spencer Cartwright) should be able to sign in via SSO but cannot access the product at all.
