I need a second opinion on this pls

So I've been DESPERATELY trying to recover my old account that I made in 2020. However, I lost access to the email and number. I've contacted roblox support many many times but failed each and every time. But I recently found the email, which may or may not be linked to the account, in a family link with my other email I'm currently using. I was able to change the password of the email so that I can log into it. But when I tried, it said that it cannot be logged in as it was part of a family link. I can remove the account from the family link and try to log in again, but it may fail and I may never gain access to it again. Do I just keep it in the family link and have limited access or just take the risk to remove it and try to log in, even though it may not be even linked with the roblox account?? Fellow users, please tell me your opinion on this
