I just updated to PhotoShop v22.4 this morning and now when I drag a layer from one .PSD to another .PSD the layer appears to move but then PhotoShop crashes. When I open the destination document the dragged image is not there.
We're sorry about the trouble with Photoshop. Would you mind telling us which operating system are you working on?
Please update Photoshop to the latest version (22.4.1) through the Creative Cloud desktop app & let us know if the issue persists. You can check how you can update the app here: https://helpx.adobe.com/creative-cloud/help/update-app.html
