Photoshop Opens but I "cannot get into"

Yesterday I was working when the eletricity went off for less than a second. It happens sometimes and those times Photoshop closes, when I open it again it just shows my works as recovered. This time I opened it as usual, I could see it opened because the icon in the app bar at the botton of the screen shows it as open. If I put the cursor over it I can see the preview of the desk (I cannot recall the exact name of it) with a recovered work but I cannot use it because it doesn't enlarge to let me work.

After closing it with Task manager and open it many times, I thought there could be a hidden window asking me something, so I hit control S to save whatever it could be and enter. I was right because a second  recovered work started showing. But I still couldn't enter. I hit again S and enter but nothing changed. I unistalled it (maintainign the preferences) and installed it but nothing changed again.

The only other thing I can say is that when I click it, a little windows shows but it should be because a little earlier I was checking the hue of a photo. I don't think it implies a reply.  This is the screenshot of the little window:

Before disinstalling Photoshop again, this time deleting the preferences, do you have any idea of what could have happened?

I use Photoshop CC latest version, Windows 10 64 bit.

Below you can see Photoshop is open with a work inside but I cannot use it.

Thank you
