Remember to back up your settings before doing the preference reset

It the “normal” reset doesn’t help try a manually remove of the preferences files. This is the most complete method for restoring to the default state. The manual method ensures all preferences which may be causing several problems. Please follow the steps below:

1. Quit Photoshop.
2. Navigate to Photoshop's Preferences folder.
   MacOS: …Users/[user name]/Library/Preferences/Adobe Photoshop [version] Settings
   Windows: …Users/[user name]/AppData/Roaming/Adobe/Adobe Photoshop[version]/Adobe Photoshop [version] Settings
   
   Note: The User Library folder is hidden by default. To access the content in the hidden folders see here:
   MacOS: Access hidden macOS library files
   Windows: Show hidden files, folders, and filename extensions in Windows
    
3. Drag the entire Adobe Photoshop [Version] Settings folder to a safe place to a backup your settings
    
4. Open Photoshop.

 New preferences files with the default settings will be created automatically.
