P: Strange color box with data loss

Why did I update it today? I resent myself. The project I made for four hours was ruined by my wrong choice. What should I do? Am I an idiot?

I really don't know what to do right now. It's so shocking right now.........................What should I do with my project?.......

I'm saved with that damaged image now. It's a PSD file, but there's even a color box on the face, so I have to start anew. What's going on right now? Holy..................................

Once I stopped working and rolled back to 23.3, the bug disappeared. An emergency update to 23.4 is required. In addition, I put the same image on my laptop and tried the 23.4 version, and the same bug occurred. I think it's broken inside the program. The graphics card driver is up to date with the Studio driver.

As I wrote in the text, it's not just "visible" like that.

It transforms the real image like that. (like a color box or a black box)

Fortunately, the PSD is preserved because I save it from time to time, but it could have been a disaster now.
