Thanks for your help. Disconnecting the metal solved the problem. True, after that it was proposed to restart the program and at the same time the entire macOS crashed, a black screen appeared on the entire computer, I had to force a reboot. This is all very strange. But anyway, now it works and opens all files.

I don't see any photos that I open in the program. Instead, a completely black screen. At the same time, I see a histogram and I understand that the photo is loaded. But why can't I see anything, what could be the problem? See attach screen.
