For security, we can't unlink or modify accounts on your behalf, and there's no support-side path to disconnect your Discord from an inaccessible account. If you're unable to regain access to the Google account through Google, creating a new Discord account to use with your current Railway account would be the practical workaround. Sorry we can't be of more help.

I do understand this is for security reasons, but the discord account that needs unlinking is the one im logged in as currently. It is possible I could provide proof of activity about the old account. Note I aim to unlink the discord account from the old railway account to the new one, the old railway account doesn't need to be recovered

We appreciate you clarifying, but unlinking your Discord from the old account still requires modifying that account on our side, which falls under the same security boundary even when the goal isn't recovering it. Proof of activity wouldn't change the outcome here. If you're able to recover the Google account through Google, you could log into the old Railway account and unlink Discord yourself. Otherwise, using a fresh Discord account with your current Railway account is the path forward. Sorry we don't have better news.
