Hi,
We're sorry about the trouble with Photoshop. Would you mind telling us which version of Photoshop you're using?
You can try the steps suggested here: https://adobe.ly/2JZDqZB
If the issue persists, please roll back to the previous version of Photoshop using the steps suggested here: https://adobe.ly/2wH0JjE
Please uninstall the latest version of Photoshop first & select the option to Keep Preferences prior to installing the previous version.
Regards,
Nikunj
