Can't export photos from Lightroom Classic v11 ("The file could not be written")

[tvs75]

I am running Lightroom Classic v11.0.1 on a Mac running macOS 12.0.1 and when trying to export photos I get the following message:

"Some export operations were not performed. The file could not be written"

I found several articles about this problem but could not find any solution.

What could cause this problem and how to fix it?

Thanks for your help!

Is the file connected? As in is the drive it's on connected?

Is the export drive full? 

It can also be a permission issue with the drive.

The photo is on the internal drive of my Mac.

The Mac storage says about the internal drive: 37 GB available of 499 GB

It was a permission issue: the desktop folder of a different Mac user account was selected.

I changed the folder and was able to export.
