UrBackup app can’t launch

I have the UrBackup app installed in ElectricEel-24.10.2.

When I click on the Play control, the status for about 15 s changes to “Deploying” and then changes back to “Stopped.” Where can I find the logs that might reveal, why the UrBackup app isn’t launching?

I removed the app and reinstalled it. That got it running. Luckily, I had not really backed up very much with it. And what I had backed up was only experimental, anyway.
