I cannot use the option "Marquee" to show the histogram of the pixel selection. This happens every time in every file. It seems when there is a selection, histogram freezes, even if I selected "Layer" option instead of "Marquee".
I've recorded a video and also uploaded the .afphoto file in the video.
I'm using Windows 10 Home, x64, version 18363, and the latest version of Affinity Photo in Microsoft Store 1.8.3.641 downloaded yesterday.
