Adobe Save for Web error - Write permission problem

[#1]

Lately, I've been running into this weird issue as I'm trying to save from psd to png (using save for web, shift + option + command+ S). The error message reads

Adobe Save for Web error

Could not complete this operation. A write

permissions issue has occurred.

A Google search about this returns nothing. Whether I'm trying to save to my desktop or to Dropbox amounts to the same error. And it seems to be doing that systematically now. My systems permissions seem to be set to read & write, so I'm really confused about this. Does anybody have an idea as to what might cause the problem? I've recently upgraded to Mac OS 11 (Big Sur), and I believe the problem began around the same time... Thanks for your help!

Hi, if you go to the security and privacy settings double check you have this

also sometimes if you reset the preferences is the solution

Thanks for your answer. As a matter of fact, I do have the permissions opened as one would expect under Files and folders in the Privacy tab of the Security & Privacy section of System Preferences.

What I found out since I posted this issue is that Photoshop seems to have changed their Save for Web functionality in Photoshop, so when I try to save using the usual keyboard shortcut Shift + Option + Command + S, it amounts to no good. But if instead of hitting S with that key combination, I hit W (as in Shift + Option + Command + W) - exporting As as opposed to Save for Web - then it prompts a different window and then I can save to png or any other format with ease.

So I guess I fixed my issue, but in the most unexpected way possible. Hope this helps others who were running into the same problem. I can't be the only one.
