I made the main account back in 2020 when I first got my PC, It was tied to my account that I had forgotten to move it into my new phone. It is still completely logged in on my PC since I set remember everything on log in. Its very troublesome for me now that I am trying to upgrade My PC I am worried that I might lose the account, there are not many games on it, but I just wanted to add it back to my PC later after I upgrade it with a new gmail address that are on my phone.

I also have tried to recover my account through the Steam Support for quite some time, but every time i try to do so, it would say that the session is invalid. Essentially I'm somewhat locked out of this account since logging out wouldn't let me back in since i have lost the Steam Guard login on my phone, the Email, and the old phone number. Should I just keep trying for the steam support, or are there other means to change my email address?
