Cannot launch Unity in Linux

I am trying to run the Unity editor in OpenSUSE but it conks out after the splash screen. I am launching Unity from the UnityHub AppImage.


The error seems to stem from GTK: `(Unity:3024): Gtk-CRITICAL **: 15:49:22.741: gtk_container_foreach: assertion 'GTK_IS_CONTAINER (container)' failed`. I am searching online but haven’t found anything. Does anyone have any ideas as how to solve this? Thanks in advance.


This the environment I am working in:


OS: openSUSE Tumbleweed x86_64

Host: 20AQCTO1WW ThinkPad T440s

Kernel: 5.5.1-1-default

Shell: bash 5.0.11

Resolution: 1920x1080

WM: bspwm

CPU: Intel i7-4600U (4) @ 3.300GHz

GPU: Intel Haswell-ULT

GPU: NVIDIA GeForce GT 730M

Memory: 12GB


The following is the error log from the editor:

```

Try my solution on https://answers.unity.com/questions...get-s.html?childToView=1803464#answer-1803464

Copy-pasted here:

Try this:

1. In your project, delete the Library folder. I found that CurrentLayout-default.dwlt in particular must be deleted, so you can try that first if your project is big and want to avoid long rebuilding times.
   
   
2. In ~/.config/unity3d/Preferences/Editor-5.x, delete the Layouts folder
   
   
3. In ~/.config/unity3d, delete the Browser folder
   
   
4. In ~/.config/unity3d, delete the Editor folder (there is one sub-folder per editor version but the serial number cannot be trivially matched with a human-readable version, so maybe just delete the whole folder)
   
   
5. Restart the project

I found 1, 2 & 3 to work in my case, and only 1+2 or 2+3 not to work. At least it should work when installing a new editor / re-installing an editor version. I also did 4 at some point so it may be needed for editor versions already installed. I did 2 at the beginning so not sure if required.
