layer mask cannot be overpainted in white, to portray the image

[Pinpin Redoï]

Once the mask is painted black, it is no longer possible to paint white to go back.

Hi @Pinpin Redoï 

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 )Win)

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.
