2014 BMW F30 N55 warm start issue: The car has a rough idle and fluctuating RPMs for the first 50 seconds only during warm starts (temp gauge in the middle), but it stabilizes completely afterward. This does not happen on cold or max hot starts. Has anyone fixed this?

My 2014 BMW F30 N55 rough idles and fluctuates RPM for the first 20 seconds only during warm starts (temp gauge in the middle). It does not happen on cold starts or max hot starts, and I already replaced the Valvetronic motor so that is ruled out. It stabilizes completely after those 20 seconds, has anyone fixed this issue before?
