We're sorry about the trouble with the Neural filters in Photoshop. Would you mind telling us which version of Photoshop are you working on? Please ensure you have the latest version of Photoshop (22.2) installed on the computer through the Creative Cloud desktop app.
You can try restarting the computer to check if that helps. If the issue persists, please try re-installing Photoshop to check if that makes a difference.
