Please sign up for a new dev org for the " Access Governance Superbadge Unit", instead of reusing org from previous unit.
The "Security Governance Specialist Superbadge" contains two units. I have signed up an org for the first unit ("Authentication Governance Superbadge Unit"), and reused it for the "Access Governance Superbadge Unit". That is root cause that I had kept getting the erorr "We can't find an expiration date for Rahul's temporary access permission". After signing up for a new org, I was able to quickly pass the challenge.
