[Test Environment for TiDB]
[TiDB Version] 7.5.0
[Encountered Issue: Problem Description and Impact] After simulating a failure and forcibly scaling down the same TiKV node, an error occurs during scale-out expansion. The error log indicates "duplicated store address: id:6005 address:"10.0.7.64:20160". Do I need to delete the faulty node on the PD node as well? If so, how should I proceed?

Because some metadata is still in the cluster, you can switch to a different port if you want to go live immediately.

You can check out this column, rebuilding kv in place:

Address conflict (reused)

When expanding, address duplication conflicts occur because the deletion operation during scaling down was not thoroughly cleaned, resulting in residual information.

Could you please explain how you performed the forced scaling down operation?

Delete first, then add.
