HDR merge shows nothing

[Hugh2908546580vc]

I selected 3 raw photos for HDR merge. When it gets to the merge window, it shows nothing. I tried to restart Lightroom, and it worked for one round, and the same problem happened again. My device is a 2023 Macbook Pro, and it's currently running MacOS 13.2.1

Hey @Hugh2908546580vc. Welcome to the Lightroom Community. I'll help you figure this out. What version of Lightroom are you working on? Is this an Apple silicon or an Intel-based MBP? What type of RAW images are you processing?

You can also go to Ligthtroom > Preferences > Performance > Use Graphics Processor > Set it to Off if it is on Custom or Auto.  

Let me know how it goes. Thanks!
