I’m not sure what is causing this, but,
the editor keep crashing after opening a project (few seconds later, i have time to click some buttons)
and sometimes even creating projects.

Fedora 29
rx 580

Application version 4.22.0.0
… built from changelist 0

OS version Linux 5.0.7-200.fc29.x86_64 (network name: localhost.localdomain)
Running 8 x86_64 processors (16 logical cores)
Exception was “Ensure condition failed: CmdBuffer->IsOutsideRenderPass() [File:/home/cristianpietrobon/UnrealEngine/Engine/Source/Runtime/VulkanRHI/Private/VulkanMemory.cpp] [Line: 2122]”

I do get a similar crash with 4.22 on one of my machines with Quadro graphics, segfaults pretty much right after the engine appears to start.

Try running the engine with -opengl4 this helps in my case.

Just enter this in the terminal: “sudo apt install mesa-vulkan-drivers” and run the editor again.
