Hi, I am having trouble with the masking tool in Lightroom Classic installed on my Windows Laptop. I have used it extensively in the past but now when iIclick on the masking tool the box flashes up and then disappears. I don't know why it wouldn't be working as I am not doing anything differently. Any ideas would be very appreciated.
Try resetting the preferences of Lightroom Classic: How to reset Lightroom Classic preferences (adobe.com)
It's recommended to backup your preferences before you reset the preferences to the default settings:
