You need to use trusted residential proxies, that's crucial. Also, better to use mobile profiles in your antidetect browser, but here's the a problem google asks for phone verification during signup, you need remove "Mobile" from the end of your fingerprint, and it will works fine. For example, change
from:Mozilla/5.0 (Linux; Android 10; K) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/144.0.0.0 Mobile Safari/537.36
to:Mozilla/5.0 (Linux; Android 10; K) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/144.0.0.0 Safari/537.36
After that you can register accounts without issues and bans. Works pretty well for me.
