Carla crashes Unreal after Make Launch (Error: VendorId, Vulkan)

[ahaider1011]

I have been using Carla for a while now in Linux. Recently, I started having issues where Unreal Engine would just crash out of no where. I am currently updated to latest Carla version 0.9.15 and UE version 4.26. I suspected there was a memory issue cause it would give several out of memory errors. I also tried build from scratch several times now. Now I have around 100GB of free space and Carla would launch but would just hang and be very slow. Ultimately crashing. During the Make Launch the following code is what I noticed in red. Any one facing this issue?

I've encountered the same issue recently as well. It's quite frustrating. Hopefully, someone in the community can shed some light on a solution or workaround.

我的系统是ubuntu20.04,ue4.26。
以下是解决方案：
1.通过以下命令检查Vulkan安装情况：vulkaninfo，没有的话会提醒安装；
2.在~/.bashrc或~/.profile文件中添加以下内容：export VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/nvidia_icd.json
3.sudo chmod a+rw /dev/dri/*
4.reboot

Could you share the output of the next command to get more information about your GPU controller?

nvidia-smi

I dont know how but the issue resolved on its own. The Unreal engine is not crashing anymore but sometimes it does. I deleted everything and resinstalled unreal engine and carla from scratch. Also I made a custom environment for python 3.10. So now its working but not sure for how long
