I tried both the rpm and AppImage. I double click and absolute nothing happens. 

I am on Fedora 42 Workstation, and I also have this problem. When launching the .rpm from terminal ( with "Cider") I get this error message: 

Gtk-ERROR **: 17:50:31.826: GTK 2/3 symbols detected. Using GTK 2/3 and GTK 4 in the same process is not supported

The .appimage doesn't launch either

I installed Ubuntu 24.10 in a VM and It seemed to work fine on it with the .deb version

I have the same issue with Fedora 42 Workstation.

We're currently investigating this issue right now, it appears to be because of an upstream Electron change where they integrated GTK 4.

After some testing we'll publish revised builds, likely just forcing on GTK 3 like this post suggests

Update: Try out the latest v3.0.2 Linux builds on Taproom, these should have the GTK flags passed in them automatically
