Unreal Editor crashes when started on Ubuntu 22.04.2 LTS

I download the Unreal Engine for Linux from the official website

The file is Linux_Unreal_Engine_5.2.1.zip and I unzip it.

I open the Unreal Editor from Bash

$ ./Linux_Unreal_Engine_5.2.1/Engine/Binaries/Linux/UnrealEditor

The Unreal Engine 5 Crash Reporter shows the following logs

Any idea to solve it?
