Rekordbox crashed after 2 hours playtime

Hi !

I `ve the following problem: I am working with a MBP 2016 Touchbar 15 inch 16 RAM GB 1 TB HDD and a DDJ 1000. RB 5.4.3 installed!

I am putting videos on. Now I have fixed that RB freezes after about 1 to 2 hours of playing time and must be restarted. It's frustrating! I tried the following 1. I switched off the touchbar (via TouchbarDisabler), 2rd Whatsapp (desktop version) switched off, 3. other firewalls etc off, 5 so far brought nothing. Videos are all bought! Xtendamix etc ...

Do you have a solution??????
