I've had a lot of trouble getting Export in PWP 8, Microsoft OneDrive, and Windows 20H2 to work happily together as I could find no way to let OneDrive back up my desktop and also to have Export in PWP 8 put a file on my desktop. It could well be that key to success is some setting that I never found, but it may be worthwhile for someone else to check that in normal circumstances, the trio does work together.

I don't use OneDrive -- I use Dropbox instead so I can't check this.

Your desktop folder is located at C:\Users\<your username>\Desktop -- it may help to navigate to the folder directly.

I just tried exporting to a subfolder of my desktop and it worked OK.

It is possible you need administrator privileges to access this folder, but I doubt it.
