The Micro Exporter does its export/file creation work at the end of the render. If you have a particularly large area to export or are using high detail settings, it will appear to hang for a while as it does this. It's still working in the background and if you check your export destination folder you can see the size of the export file increasing. It's recommended that you not use detail settings above 0.5, and in many cases not above 0.25, when doing geometry exports.
