Save for web Error

[Martin Alvez]

Hello,

I have the latest Photoshop v 20.0.9 on a Mac Catalina v 10.15.2. 
Every time I try to export a picture on the SAVE FOR WEB I get an error. ("Could no complete this operation. An unknown error has ocurred.")
How can I fix this? 

Thanks,

Martin

I Solved updating it to the Latest Photoshop Version, the v 21.1.1

So if others have the same problem try updating for this version.
