Application not running through Lightpad

I was trying to run “Disks” through Lightpad today, but it won’t open.

The problem does not occur when I use any other launcher.

Can somebody reproduce?

I tried both from the applet and running lightpad manually via the terminal (com.github.libredeb.lightpad) and disks was launched OK.

So - sorry - cannot reproduce your observation under UB 20.04.
