Is the PlayStation project forbidden, and is it the cause of problems in one's livelihood and the non-acceptance of prayers, or are previous sins the cause?

Tightness of hand and financial hardship may be a trial, not a punishment, and a Muslim must be patient and supplicate. As for the ruling on opening a PlayStation game center, it depends on the games offered. If they are free of prohibitions such as gambling, and do not involve any Sharia violations, then it is permissible to work in it. Otherwise, it is not permissible, based on the Almighty's saying: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression."
