In curves (command M) cycling through the c,m, y, k by using the command 3,4,5,6 this error pops up and closes out the curves palette. I just upgraded to the newest version of photoshop today and I’m getting this message quite frequently. not every time though.  version 27.4.0 Mac version

      Hi ​@dianer_macperson 

       

      1. Try resetting Prefs for the Beta:
      /Users/yourname/Library/Preferences/ Photoshop Beta Settings (Mac Ventura)
      /Users/yourname/Library/Preferences/Adobe\ Photoshop\ \(Beta\)\ Settings (Mac)


      C:\Users\user name\AppData\Roaming\Adobe\Adobe Photoshop (Beta)\Adobe Photoshop (Beta) Settings


      Launch BETA Photoshop While Pressing The Keyboard Shortcut
      With Photoshop closed, press and hold Shift+Ctrl+Alt (Win) / Shift+Command+Option (Mac) on your keyboard and then Launch Photoshop the way you normally would.

      2. It may help if we could see your Photoshop beta System Info. Launch Photoshop beta, and select Help >System Info...and copy/paste the text in a reply.  

      Thanks,
