Rockstar Social Club Locked Me Out of RDR 2 and GTA V Despite Logging Into Steam

I can't play my RDR 2 and GTA V games on Steam because of a frustrating application called Rockstar Social Club. My email linked to Rockstar Social Club was hacked, so I changed all my registered emails, including Steam, to a new one, recovered my accounts and apps, and then deleted the old email to avoid further issues. Now, when I try to log in to these games via Steam, it insists I log in with the original email I registered with on Rockstar Social Club—but that email no longer exists. When I attempt to log in, it sends a confirmation code to the deleted email, which I obviously cannot access. I have repeatedly contacted Rockstar Support about this issue, opening multiple tickets, but they keep asking the same questions and refusing to help, claiming they can't verify my account ownership. They demand a purchase receipt sent to the original email, but again, that email no longer exists. I’ve provided them with the email password, login history, device details, and location data linked to the Social Club account, but they still refuse to assist without the receipt and username. The username is something I must have set up randomly months ago, making it impossible for me to recall now. In summary, I can log in to Steam but can't play the games I purchased due to Rockstar's inflexible and unnecessary policies. Their lack of support has been infuriating. You can be certain I will never purchase a Rockstar game again. This experience has been utterly ridiculous.
