Problem between Camera Raw and Photoshop

Hello.

I have several problems when working with Raw files in Photoshop CC 2017.

When I click on a raw file, Photoshop open, then camera raw open too. ok...
I can do all what I want with camera raw on the file. ok...

I can register the new file (jpg,...). ok...

But :

- Photoshop can't open a new file after this work

- I have to close this app, because it is bloqued
- There is no small attachment file to the original raw, registered in my photo repertory. So my operations where not registered. If I want to make some change in the raw file, I have to start all the work from the begining...

I have uninstalled Photoshop and installed it again, but no change...

Thank you for your help.
