Yesterday I lost over an hour's work, today I fortunately saved before trying to pick a color from a lower layer. It was covered by a duplicated layer, I had a glow on the lower layer for a halo effect. The freeze did not occur when picking colors from other layers. After restarting the program, I was able to get the color I needed from the duplicate layer on top. Has anyone else encountered this problem or have an idea what might cause it?

I'm using a Windows 11 system on a relatively recent LG laptop with good specs (16 GB Ram) - it has an Intel graphic card which isn't ideal, but this is the first problem I've had. I use a Huion 16 2021 graphics tablet with display. It made no difference if I selected the color with Alt + mouseclick or Alt + tap with stylus.
