File > Open and File > Open Recent behave as expected.
This started happening abruptly while I was using Photoshop 21. I have no idea what caused this fault.
I tried deleting the preference files. This made no difference. I discovered that CreativeCloud was showing a blank screen. I disinstalled CreativeCloud and reinstalled it. It then offered to update Photoshop to 22.1, which I did, updating CameraRaw at the same time.
Photoshop 22.1 is still not responding in any way to File > New.

Resolved the problem by a bodge:[Note how your preferences are set in Preferences]Close PhotoshopWindows - navigate to C:\Program Files\Common Files\Adobe\UXPMacOS - navigate to Macintosh HD/Library/Application Support/Adobe/UXPThen rename the UXP folder to ~UXP.Open Photoshop [and reset the Preferences to what you want]
