Photoshop 2020 export as error: An Unknown error occurred

 Yes workes fine, this 22.1.1 release fixes the problem! Thank you. I installed it and I already run the test with a very heavy monster level file and it came out perfectly. 🙂

This needs a fix! Most of the time Photoshop (latest version PC 21.1) works fine - then randomly I get the "unknown error" and I am unable to save/save as/quick export/export as - I can't even flatten the image/merge down/merge visible. Guess all I can do is roll back to a previous version and try that as others have suggested -___-.. no replies from Adobe, no acknowledgement of this error even existing that I can see - with SO many people and companies worldwide paying for a subscription and they still can't fix this coming up on a year later - but they have time to come out with iPad apps (that are also super borked). Sigh /endrant.

I'm still struggling with this. 

Please fix, Adobe. Please.

It's definitely annoying but I found that if I just go in (after having problems saving it as a basic psd file) I go and flatten all the layers and can quick export as a png. It works-ish but the only thing is that I havent figured out how to save it with a transparent background. Also might be working off off a later version but judging by some other comments, that isn't really the issue. [insert eyeroll]

I was just having the same issue, when i tried exporting(Export As) my document. Uninstalled Photoshop and reinstalled (I have the latest version), changed preference etc and nothing. I am now able to export after reading:

Error: Image is outside of the document bounds

It seems like the problem was my layers being outside so I cropped them. Maybe it will work for you as well 

Hi, I was about to export to art I did, and it gave me this error I already tried everything that the community suggested, but nothing changed. Please fix this bug. Thanks:

I'm having the same problem, I tried to make a quick png export but it doesn't work too, I also tried to close all adobe programs in the task manager but the problem persists, it seems that going back to an old version is the solution. Adobe, please fix. 

Thanks to Reddit, you have to make all layers not visible by clicking on the eye, then create a new empty layer, lock it. Select it and have nothing else selected. Then save. It WILL work. Just try it. Unfortunattly, then your artboard will have blank images, but I read someone said something about that. 

I AM HAVING THE SAME ISSUE, SAME EXACT DAMN ISSUE!! I updated just a few days ago and now I get the same message as typed in the original post's description. Do I need to downgraade one version? Will I lose my work? 

This is for my supervisor who is releasing a new film and it's holding both of us up, delaying his release and my workflow. 

I feel unsure about going back one version since I may lose my work. What should I do? I need to export at least in high def proofs for my boss but don't want to send him screenshots or "save for web" version.
