Unfortunately, NG, it's the only answer anyone can provide, since if you've enabled 2-Step authentication with a Microsoft Personal account, the form Microsoft provides to recover your account can't be used, so since Microsoft has also removed the ability for Microsoft Support to access personal accounts to protect them, the only way to recover is either performing the appropriate Authenticator Recovery process from the backup of that data in your Google or Apple account which you must have made previously, or by using at least 2 other verification methods which are still valid like username/password, alternate email, text message to phone or Microsoft Recovery code.
Restore account credentials from Microsoft Authenticator - Microsoft Support
This attempt is best done from a Windows device that's been registered with your account in the past, which should be recognized as one factor and preferably one using Windows Hello Face (camera), Fingerprint or PIN, which are already considered 2-Step together.
If that's not possible, then using a Microsoft Edge browser (avoid anything 3rd-party like Chrome) to login using your password, then using either alternate email or text of a code as the 2nd-Step, should be enough to allow access to make the change necessary to remove both the Authenticator's 'Send sign-in notification' option, as well as the 2-Step setting turned Off until you're sure you've got everything fixed and working again.
If you didn't back up the authenticator previously and don't have at least 2 other methods available to try and use from either a registered Windows device using Edge to access your account or entirely from scratch using your username/password and alternate method, then no one can help you recover the account, since 2-Step means exactly that and no method exists to recover without them.
