Trying to play on a 2019 Mac Pro with an AMD 6900 XT. Every time I hit Play a black window opens and the entire computer freezes, has to be rebooted or if you wait long enough it will reboot itself. Tried reinstalling several times nothing changes it does it every time. Mac is on the latest version of Big Sur. You can move the mouse around for a bit but you cannot click on anything and after a bit it freezes as well.
