Copy Settings Interrupts AI Denoise Background Processing in Lightroom Classic 15.4

So if I select 10-20-50-100 images, doesn’t matter, and I apply AI denoise to all of them, Lightroom Classic starts doing the AI denoise in the background. I can go to the develop module, start editing any other images, I can even use the previous button, etc. 

BUT the moment I copy settings from one image to another, the AI denoise in the background stops and it stays in that stuck position. I can’t edit any of those images until I restart Lightroom Classic. When I hit the copy settings button(on the keyboard), it finishes the denoising on the current image that it has been doing, but it does not continue on the next photo. Everything just stops.

So basically if you apply AI denoise to images with copy and paste settings, then you can’t use the copy settings function until the denoise process finishes.

Only workaround is to use sync settings for AI denoise and then you can work with copy settings and paste settings on another images in the meantime.
