Friends and colleagues, we've already written here in the chat about a temporary solution to the problem, and I'm still working without any problems and my processing speed hasn't dropped. All you need to do is turn on the CAPSLOCK and instead of the right arrow, press the button (1), then you will not have any problems with switching to another photo. If you want to go back to the photo, press the left arrow, not the (0) button. Those who make selections not by color, but by numbers will not have problems, I do it only 1, if you do it with different numbers, then after you have made a selection and you need to start processing, you can simply put a red marker (6) on all selected photos, for example, with number 2, and so for each number do it in different colors! Then, after processing, return to the photo with the red marker and put the number (2) on all the photos again. This is all done in the LIBRARY mode, just select all the photos marked with the red marker and click (2), that's it, your photos are marked again the way they should be. So, it's not difficult to do, it doesn't affect the speed of the process, and then we wait for ADOBE to fix the bug! Enjoy)
