Basecamp will no longer backup on my MAC. I have not changed any settings and I do not receive any error messages. Basecamp simply locks up and the Force Quit command must be used every time to restart the program. I've restarted the computer and all of the latest MAC software updates (MAC OS Catalina 10.15.04) have been installed. basecamp also locks up when I attempt to export and tracks from My Collection. I am still able to send tracks to my device and import tracks into My Collection.
