P: Save For Web error A write permissions error has occurred Photoshop 22.1.1

It's comforting that this topic is 4 years old and people are still having issues. And it's not just a Dropbox thing. This also happens with OneDrive. I'm not sure if I should blame Adobe or Apple... I'm leaning towards Apple because my old Mac with all the same settings (except for an older OS) never had this error.

I'm just here to thank Greg Harbour. I know it's been two and a half years since his answer but that answer really saved me. I'm, also running into the Permissions issue - because the company that I work for has all of us now set to automatically backup to OneDrive - which I believe is causing one of the conflicts. By skipping the save and just using the preview gif - which is the same thing - it probably saved me hours and hours of frustration and it's genius simple. Thanks!!

I get this error intermitttently and I haven't been able to figure out the cause. It's something to do with OneDrive but I don't understand why it works ok for a while then the problem returns. The organisation I work for manages my laptop and I can't make changes to settings.

Don't worry about disabling Dropbox backup

Photoshop was still not able to <Save for web> with Dropbox backup enabled for me. Plus it's fiddly and inconvenient to toggle off and on.

Workaround

1. In Photoshop <Save for web>
2. Click <Preview> button bottom-left; your animated GIF will open in your default browser
3. Right-click the gif in the browser and <Save image …> either to Downloads or nominated folder

What if this happens when you don't have Dropbox or GoodSync?
OS Ventura 13.4

I was able to fix this issue by re creating the user profile... well see if it breaks again.

I am having this same issue and followed all the instructions. Gave Photoshop full disk access on my mac. Also installed and updated Mac OS and Photoshop.

It seems to be a bug with Adobe, which seems to happen quite often I am sorry to say. 

Used Premier to create the Gif and compressed it with https://ezgif.com.

Please advise when the bug will be fixed. Thanks.

I'll add my "it worked for me" to disable the dropbox backups. I turned them back on and it seems to be working still.  What a weird little problem. I would have never figured this one out. 

Two years on and this is not fixed? I'm getting it today on PS 24.1 and Ventura 13.2.1

Another option (after I tried EVERYTHING, to no avail). I did Export>Save for Web>Save. BUT I saved to a folder, not my desktop and the error triangle disappeared. OMG Adobe please fix this. I spent two hours messing with the issue.
