In this situation, the person needs to reconnect with the reasons that led them to stop gambling in the past. If they started gambling again despite knowing about their addiction, it shows that they're still struggling internally. The right thing to do would be to seek support, whether professional or from those close to them, to overcome this phase again.
If he has received support and attention from some concerned parties, he may have thought about it again,
but if he enters only because of his addiction, it will only cause new problems.
You should not go in with old mistakes that have been left behind and try to play with new accounts and new personalities in gambling,
so that you know what makes you an addict and what to avoid so as not to fall into the same mistakes.
