Can't access Github Student Developer Pack Token : 763830

Hello 1Password Support,

I am a verified GitHub Student (Student Developer Pack) and I am trying to redeem the 1-year free 1Password offer at:https://1password.com/developers/students

When I click “Sign in with GitHub”, GitHub authorization succeeds (callback URL includes code and state), but the page shows:

“Something went wrong — We weren't able to authenticate with your GitHub account.”

Browser console shows: States not provided

I already tried:

• Private/incognito window, single tab only
• Multiple attempts
• Not using VPN
• Desktop 1Password app left alone (not the issue)

My support ticket ID is “763830”

Please help activate the GitHub Student Developer Pack promotion on my account manually.
