Did you try to recover your google account with text message option?
It is possible only if you verified/added your mobile number to your google account, this looks simple way but it only work when you have the mobile number added.
I mentioned that in op already.
Really? Or I am missing to read that part again?
Please highlight or bold those part which you mentioned in OP about recovering through text message codes which will send to our mobile number.
"I had disabled recovery phone number to make myself safe from sim swapping attacks and no recovery email either."
