Ensure condition failed, can't launch Carla about carla HOT 9 OPEN

This issue is known and Carla should start if you press play in editor

from carla.

Can't press play, becaus if i make launch, carla does not open

from carla.

What happens when you make launch?
It gets stuck at 95%?

from carla.

Yes,

That ensure condition does not block anything. It is common to see it but does not block anything.

We need info about what happens after that. Please forget about the ensure
If it is stucked at 95% plese, let it work as Unreal is compiling Shaders.

It loads up to 95% and then the UE loading screen disappears. I do not stop the process.

That issue is related to Unreal Engine with vulkan. I suggest you to retry until it works and shaders are compiled or downgrade nvidia drivers and continue trying,

from carla.

With the nvidia-470 driver I can now start carla with make launch, but it crashes when i hit play. I don't know if this is still related to the original problem. Here are the error messages:

from carla.

Please have patient. Those are warnings, not error messages. They are not important. Then, please wait 10-15 mins before pressing play, Unreal is still compiling when it starts, make launch, wait for 15 mins or until console says is not compiling shaders and try again
