Car does not start in warm condition on the first start attempt, only on the second attempt

Hello, my wife currently has a problem with your Volvo V70 T5. If the car is issued in a warm way and is to be restarted afterwards, it usually does not jump on but only comes up to about 500 revolutions and goes out again. On the second attempt it then starts completely normal. Does anyone have an idea what could be? The air mass meter was changed only last year.
