Describe the bug

The attribute tables of the vector layers that come with the Natural Earth Sample dataset that you can install from within GRASS GIS are not readable. Trying to open gives an error message (see screenshot below). After dismissing the error message, an empty attribute table opens. The same is true if you download (presumably the same) dataset from the website and for the full world dataset.

To reproduce

1. Open GRASS GIS, go to the data panel
2. Select the Download Sample Project option
3. Select the Natural Earth sample dataset and download
4. Open any of the vector layers
5. Open the attribute table of the vector layer

Additional context

Reporting here because it influences the experience of grass gis, but perhaps better to report in the grass-website repository?
