Can't Access My Google Account After Reset – Security Code Issue

I made the mistake of resetting my phone without first removing my Google account, which has now left me unable to log back into my account. Whenever I attempt to access it, I am consistently asked for a security code over and over again. Regrettably, I am unable to receive the code as my Google account is not linked to another device and is not connected to my phone number.

Are there alternative methods to regain access to my account? I need immediate assistance in recovering access. I urgently need your assistance. The matter at hand is of utmost importance and requires immediate attention.
