problems language

Hi, is it possible that you have two different versions installed in two languages? 

You can select the install language in the preferences of the CC application:

https://helpx.adobe.com/be_en/creative-cloud/help/change-install-language.html

Then you switch the language from the Edit>Preferences>Interface menu, with a restart.

Is it possible that your preferences do not stick/get erased and that you get a fresh start page?

The images listed in the home page are just that, a list of the recent files.

The files should still be in the folders they have been saved to, can you check in Files explorer?

Could you record the operation where the image gets deleted?

Also, please post the contents of Photoshop's Help>System Info... menu, so that we get to know your OS, its version, the exact version of Photoshop you are running, the date of the GPU driver, etc.
If your post disappears, do not repost it, as it might need to be approved by a moderator. As an alternative you can save it to a .txt file on your computer and attach it on your answer via the forum. (attachments do not post from e-mail)

Hello,

Do you know in which language is your Adobe Account is set in?
Here are my settings

You can find them if you access your Adobe account (when you click on your avatar, top right of the CC app for example, then go to "account settings" and then scroll down to access your languages.)

Let me know if that helps!
