I have also encountered this situation, that is, when I use the clear document, I will delete the latest document in Ps by the way. Not only that, the interface layout of my entire Ps has also become the default interface layout, but the original layout is still there, so I wonder why it disappeared. Later, it was the same old problem when I turned it off and turned it on again. No choice but to change the original Adobe Photoshop folder to Adobe Photoshop_ backup, and then reinstall Adobe Photoshop. The result is good, and the newly created folder is still preserved.

I suggest you reinstall it.

Do you think your document was saved with my latest document? If so, you may have used a cleaning tool.

For example, the master of optimization, when 360 cleaned up the garbage, when the C disk was slimmed down, the temporary files inside were deleted.

If you can't find it back, be careful not to delete the recently used documents when optimizing slimming in the future!
