Can reproduce on openSUSE Tumbleweed. Does not seem to be the same issue as Bug 412986 as the symptoms are a bit different (something is printed to the console this time).

*** Bug 435661 has been marked as a duplicate of this bug. ***

Comment 3 Nate Graham 2021-05-17 15:54:25 UTC

This seems to be working for me now. All apps tested launch via the button, except for Blender. I suspect that to be a packaging issue.

Comment 4 Aleix Pol 2021-05-18 02:04:14 UTC

No error message on the terminal for blender?

Comment 5 Nate Graham 2021-05-18 02:38:48 UTC

Nope, nothing at all. :(

What's weird is that Blender briefly shows up in the task manager with its launch feedback animation and then it disappears, but the app isn't launched.
