Blockchain.com Returned BTC Deposit; Account Now Unverified — Unable To Re-verify

I have been a verified user of Blockchain.com for a long time and had successfully completed account verification in the past. Recently, a BTC transaction that was previously stuck was returned to my account, which I appreciate. However, at the same time my account status was unexpectedly downgraded from verified to unverified. Now, whenever I attempt to re-verify my account, I receive an error message and cannot proceed. Could you please explain the reason for this issue in detail and provide a solution? This situation is very concerning as I need access to my funds urgently. Please review my case and restore my verified status so I can withdraw and use my balance. Thank you for your urgent assistance.
