SD hangs on launch in Catalina

[JohnTynes]

I upgraded my Mac Mini (late 2014) to Catalina a few days ago and since then, SuperDuper 3.3.1 hangs on launch. Both windows render (main window and scheduled copies window) but then the app just hangs. I deleted SuperDuper and did a fresh install from your website's installer and got the same results. I then tried deleting my scheduled copy Library file and my settings but still got the same results.

Because I used Force Quit, I was able to submit a crash report to Apple with my notes and hopefully you'll see that.

For now I am unable to use SuperDuper at all under Catalina.

No, we don't get things you sent to Apple. If you could, please sample the application with Activity MOnitor and send the sample log to support - don't post it here - and we'll continue there.

Update: After I deleted prefs and other user files in /Library (user and root), and restarting, SuperDuper began working normally again.

Unfortunately, though, now we don't know what was going on...

Exactly the same problem with my iMac 2015. I send sample log to support.

Then we've definitely replied...because I've replied to every message before this particular post.
