    • What is the solution? Is there a MS update/patch that resolves this issue?
      The smart card team had closed this issue, stating it was "By Design".

      However in my instance, I have 2 computers one works and one does not:

      Computer 1 is hardened. Edge never displays PIN GUI and crashes with Error Code 500. Could we be missing an update as we mainly push critical and security updates? If so what update?

      Computer 2 is NOT hardened but has all available updates and Edge works fine with Smart Cards Authentication.

    • Hello,

      Thank you for providing this information about the issue. This case is resolved as “By Design” due to Edge hardening and security limitations. We do not plan to release a fix for this problem currently; however, we are taking your suggestion into consideration for a future build.

      Best Wishes,
      The MS Edge Team
