How about you elaborate on your problem so we can potentially help instead of being rude to someone attempting to give you advice on how to fix your issue.
Is the AI fouling out? The opponent? Your teammates? The players you're using? What sub settings are you using? Auto? Manual? Is it happening in MyCareer? MyLeague? Play Now? Online? MyTeam?
You can't expect helpful responses when all we have to go off is an angry rant.
I've not once seen anyone foul out at the half in 2k19 or even 2k12-2k18, so what you're experiencing is not commonplace for a majority of us.
