Account hacked. No course of action

My channel , my Gmail and everything was hacked. 2fa did not work they managed to get around that. They changed my phone. My pass. Added a USB security key. They even somehow forced logged me out. I tried every single account recovery option. They changed my entire channel into this telsa crypto scam shit and I'm just at a loss. I have a viral video or 2 and I'm very well known for the starting the whole "mewing' trend

My name is astrosky. I tried messaging twitter youtube. I tried every single option out there

How the fuck is 2fa this useless now and how did I get my account hacked. They removed everything I ever uploaded. I can't get in. What options do I have? How can YouTube no fix this yet? How? Please. Someone hook me up to someone or give me options.....
