Basecamp crashes/freezes when trying to export a GPX file

Good evening,

 

I'm trying to export a small collection of tracks and waypoints using the export function under the file menu. When I do this basecamp freezes and I have to force quit to exit the program.

I've tried rebooting my system and the issue is still present

MAC O/S Catalina 10.15.4

Basecamp version 4.8.8

and I"m trying to export the file as a GPX v1.1 file type

Thanks

Raymond
