My Clash Royale Account Locked, Unable to Recover Despite Providing Account Info

My Clash Royale account has been locked, and I’ve tried reaching out to support through another account, providing my account name, trophy count, and clan name. However, I received a message saying, "We couldn’t complete the recovery process." I’ve spent years building this account, and now I’m worried about losing all my progress. The issue isn’t finding my Supercell ID email—it’s that my account is locked. What can I do to resolve this and regain access to my account? I need a solution as soon as possible.
