This happened also in older Versions of Lumetri. When i use the Color Picker in Lumetri and i accidently put the ColorPicker to the Programm Output Monitor (selected via Videooutput and via HDMI), it just beeps and i can't go to the small Programm Monitor to select a color. I can now do whatever i want, everytime i click some thing, Premiere just beeps. I have to hard Shutdown the Programm, which always loses some work. This is very annoying. Any Help? Or a workaround?
I'm on a maxed out macbookpro 2018 with a blackmagic egpu, where the programmonitor is plugged in via hdmi.
