Can't save any file on Photoshop 2020

[Nermine]

If anyone could help me. It keeps opening this window with no response, I tried to re-open the photoshop and redo the work and re-save and it is always the same.

Hi there,

We're sorry about the trouble with Photoshop while trying to save the files. Would you mind sharing the version of Photoshop you are using along with your computers operating system?

Have you tried to re-install the application to check if that helps? You can also try to reset the preferences of Photoshop using the steps mentioned here: https://adobe.ly/2Qzc0K3

Please backup your settings prior to resetting the preferences. You can check: https://adobe.ly/2vNz6FG

Let us know how it goes!

Regards,

Nikunj

Does the document open or do you have to kill Photoshop because it hangs?
