Export has troubles exporting assets

Hi,

I'm trying to export my work to .png, but I receive the following error: There was a problem exporting 11 assets. That is basically all the assets. (artboards) I have tried to export just a single artboard, but the same problem occurs.

I have tried to export to .pdf and .svg, but no luck there.

I have checked that the folder where I'm saving to is a read and write folder. And I have checked that the document isn't bigger than 16.000 px.

Now, I'm out of ideas.

I have used a few images in the artboards, but the export of artboard with no images failed a well.

I have copy / pasted an icon made in illustrator, but when I tried to export a artboard without it, the same problem occurs.

Can anyone help me?

Thank you,

Janneke
