Unable open PSD: "unexpected end of file" error

If you have Adobe PhotoShop you can repair it by changing the damaged images / layers.

Sorry to hear about that. You can try to recover the Photoshop file by using some methods recommended in this guide: 5 Proven Methods to Recover Photoshop Files on Mac and Windows Hope it can help you!

try to open that .psd file in photoshop cs5 or cs6 version

If the file is corrupted, there's nothing you can do short of finding another copy of the file.

I suggest the following which worked for me.
Open the Photoshop program folder and open the Plugins folder. Move all the plugins to a separate empty folder on your desktop. Be sure there are no files in the Plugins folder
Next restart Photoshop 2015. If it opens correctly replace the plugins, one by one, into the Photoshop Plugins folder and restart Photoshop 2015 after each individual replacement. When Photoshop 2015 stops starting correctly you have found the offending plugin(s).
After doing the above I found two plugins that caused my problem. Downloading updates for the offending programs that were created to solve Photoshop 2015 plugin problems and installing them solved the issues for me so I can use those plugins again.

Also I found this program Photoshop Fix Toolbox https://www.fixtoolbox.com/photoshopfix.html

I don't think I've ever seen a PSD file corrupted on disk myself. Often it's a sign of system instability. Did you have a crash or power failure while it was saving (keeping in mind that it may appear to finish before it's actually all the way saved to disk)?

Are your disk hardware and file system healthy? Look in your event logs for any indications of failures.

Unfortunately it might be that either there was an update that messed up your file, or that your file got corrupted. Make sure the extension matches what it's supposed to be, just in case it just got renamed (google "show file extensions" with your operating system to find out how to check this). Hopefully you kept a backup, because it doesn't really look good.
