Thanks for the detailed report. We believe this is fixed by PR #7479, PR #8240, and PR #8248.

The screenshot identifies the rejected redirect as t3code://app/CLERK-ROUTER/VIRTUAL/sign-up#/settings/connections. This is the exact native OAuth virtual-route leak fixed upstream, not a generic GitHub OAuth configuration error. Main has the native transport fix, the later Electron virtual-router fix, and removal of the stale Clerk UI pin that blocked the stable OAuth transfer fixes. No post-update failure is reported.

I'm closing this as fixed as part of an automated pass on all open issues. If this still happens in a current build that includes PR #7479, PR #8240, and PR #8248, please reply with the T3 Code version and fresh logs or reproduction details, and we can reopen it.
