Bridge 2021 export panel not working

Bridge 2011 was workign fine to export, suddenly started to stuck in half progress on a batch and now stopped completly, process start but stay stuck forever.

Here is what Lumigraphics is talking about.

The whole export workflow is convoluted. 

You need to have the export panel open.

You drag your files to the preset export you want to use. I have 1 file for DNG export.

At the bottom is your export button.

Good luck we are all counting on you.

Do you have the export panel open?
