[DX12] Still crashing to desktop every 30-60min

So since they made DX12 standard last season the game crashes directly to desktop every ~30 minutes. Without error message, just to desktop, no error log, nothing. Then I switched to DX11 and everything was perfect but the DX11 support comes to an end at mid season so I'm forced to switch to DX12 again. Switched today, tried to play and AGAIN. Crash to desktop every half an hour or every second game, I can't say exactly. But it's super annoying that this is still a problem. Does anybody else have constant crashes to desktop with DX12? This is unplayable like this...
